text: Pleiotropy is the well-established idea that a single mutation affects multiple
phenotypes. If a mutation has opposite effects on fitness when expressed in different
contexts, then genetic conflict arises. Pleiotropic conflict is expected to reduce
the efficacy of selection by limiting the fixation of beneficial mutations through
adaptation, and the removal of deleterious mutations through purifying selection.
Although this has been widely discussed, in particular in the context of a putative
“gender load,” it has yet to be systematically quantified. In this work, we empirically
estimate to which extent different pleiotropic regimes impede the efficacy of
selection in Drosophila melanogaster. We use whole-genome polymorphism data from
a single African population and divergence data from D. simulans to estimate the
fraction of adaptive fixations (α), the rate of adaptation (ωA), and the direction
of selection (DoS). After controlling for confounding covariates, we find that
the different pleiotropic regimes have a relatively small, but significant, effect
on selection efficacy. Specifically, our results suggest that pleiotropic sexual
antagonism may restrict the efficacy of selection, but that this conflict can
be resolved by limiting the expression of genes to the sex where they are beneficial.
Intermediate levels of pleiotropy across tissues and life stages can also lead
to maladaptation in D. melanogaster, due to inefficient purifying selection combined
with low frequency of mutations that confer a selective advantage. Thus, our study
highlights the need to consider the efficacy of selection in the context of antagonistic
pleiotropy, and of genetic conflict in general.

text: "In the first part of this thesis we consider large random matrices with arbitrary
expectation and a general slowly decaying correlation among its entries. We prove
universality of the local eigenvalue statistics and optimal local laws for the
resolvent in the bulk and edge regime. The main novel tool is a systematic diagrammatic
control of a multivariate cumulant expansion.\r\nIn the second part we consider
Wigner-type matrices and show that at any cusp singularity of the limiting eigenvalue
distribution the local eigenvalue statistics are uni- versal and form a Pearcey
process. Since the density of states typically exhibits only square root or cubic
root cusp singularities, our work complements previous results on the bulk and
edge universality and it thus completes the resolution of the Wigner- Dyson-Mehta
universality conjecture for the last remaining universality type. Our analysis
holds not only for exact cusps, but approximate cusps as well, where an ex- tended
Pearcey process emerges. As a main technical ingredient we prove an optimal local
law at the cusp, and extend the fast relaxation to equilibrium of the Dyson Brow-
nian motion to the cusp regime.\r\nIn the third and final part we explore the
entrywise linear statistics of Wigner ma- trices and identify the fluctuations
for a large class of test functions with little regularity. This enables us to
study the rectangular Young diagram obtained from the interlacing eigenvalues
of the random matrix and its minor, and we find that, despite having the same
limit, the fluctuations differ from those of the algebraic Young tableaux equipped
with the Plancharel measure."

text: 'Computer vision systems for automatic image categorization have become accurate
and reliable enough that they can run continuously for days or even years as components
of real-world commercial applications. A major open problem in this context, however,
is quality control. Good classification performance can only be expected if systems
run under the specific conditions, in particular data distributions, that they
were trained for. Surprisingly, none of the currently used deep network architectures
have a built-in functionality that could detect if a network operates on data
from a distribution it was not trained for, such that potentially a warning to
the human users could be triggered. In this work, we describe KS(conf), a procedure
for detecting such outside of specifications (out-of-specs) operation, based on
statistical testing of the network outputs. We show by extensive experiments using
the ImageNet, AwA2 and DAVIS datasets on a variety of ConvNets architectures that
KS(conf) reliably detects out-of-specs situations. It furthermore has a number
of properties that make it a promising candidate for practical deployment: it
is easy to implement, adds almost no overhead to the system, works with all networks,
including pretrained ones, and requires no a priori knowledge of how the data
distribution could change. '

text: We present a thermodynamically based approach to the design of models for
viscoelastic fluids with stress diffusion effect. In particular, we show how to
add a stress diffusion term to some standard viscoelastic rate-type models (Giesekus,
FENE-P, Johnson–Segalman, Phan-Thien–Tanner and Bautista–Manero–Puig) so that
the resulting models with the added stress diffusion term are thermodynamically
consistent in the sense that they obey the first and the second law of thermodynamics.
We point out the potential applications of the provided thermodynamical background
in the study of flows of fluids described by the proposed models.

text: We investigate the ground-state energy of a one-dimensional Fermi gas with
two bosonic impurities. We consider spinless fermions with no fermion-fermion
interactions. The fermion-impurity and impurity-impurity interactions are modeled
with Dirac delta functions. First, we study the case where impurity and fermion
have equal masses, and the impurity-impurity two-body interaction is identical
to the fermion-impurity interaction, such that the system is solvable with the
Bethe ansatz. For attractive interactions, we find that the energy of the impurity-impurity
subsystem is below the energy of the bound state that exists without the Fermi
gas. We interpret this as a manifestation of attractive boson-boson interactions
induced by the fermionic medium, and refer to the impurity-impurity subsystem
as an in-medium bound state. For repulsive interactions, we find no in-medium
bound states. Second, we construct an effective model to describe these interactions,
and compare its predictions to the exact solution. We use this effective model
to study nonintegrable systems with unequal masses and/or potentials. We discuss
parameter regimes for which impurity-impurity attraction induced by the Fermi
gas can lead to the formation of in-medium bound states made of bosons that repel
each other in the absence of the Fermi gas.

text: Motivated by recent experimental observations of coherent many-body revivals
in a constrained Rydbergatom chain, we construct a weak quasilocal deformation
of the Rydberg-blockaded Hamiltonian, whichmakes the revivals virtually perfect.
Our analysis suggests the existence of an underlying nonintegrableHamiltonian
which supports an emergent SU(2)-spin dynamics within a small subspace of the
many-bodyHilbert space. We show that such perfect dynamics necessitates the existence
of atypical, nonergodicenergy eigenstates—quantum many-body scars. Furthermore,
using these insights, we construct a toymodel that hosts exact quantum many-body
scars, providing an intuitive explanation of their origin. Ourresults offer specific
routes to enhancing coherent many-body revivals and provide a step towardestablishing
the stability of quantum many-body scars in the thermodynamic limit.

text: In 1915, Einstein and de Haas and Barnett demonstrated that changing the magnetization
of a magnetic material results in mechanical rotation and vice versa. At the microscopic
level, this effect governs the transfer between electron spin and orbital angular
momentum, and lattice degrees of freedom, understanding which is key for molecular
magnets, nano-magneto-mechanics, spintronics, and ultrafast magnetism. Until now,
the timescales of electron-to-lattice angular momentum transfer remain unclear,
since modeling this process on a microscopic level requires the addition of an
infinite amount of quantum angular momenta. We show that this problem can be solved
by reformulating it in terms of the recently discovered angulon quasiparticles,
which results in a rotationally invariant quantum many-body theory. In particular,
we demonstrate that nonperturbative effects take place even if the electron-phonon
coupling is weak and give rise to angular momentum transfer on femtosecond timescales.

text: Cells need to reliably sense external ligand concentrations to achieve various
biological functions such as chemotaxis or signaling. The molecular recognition
of ligands by surface receptors is degenerate in many systems, leading to crosstalk
between ligand-receptor pairs. Crosstalk is often thought of as a deviation from
optimal specific recognition, as the binding of noncognate ligands can interfere
with the detection of the receptor's cognate ligand, possibly leading to a false
triggering of a downstream signaling pathway. Here we quantify the optimal precision
of sensing the concentrations of multiple ligands by a collection of promiscuous
receptors. We demonstrate that crosstalk can improve precision in concentration
sensing and discrimination tasks. To achieve superior precision, the additional
information about ligand concentrations contained in short binding events of the
noncognate ligand should be exploited. We present a proofreading scheme to realize
an approximate estimation of multiple ligand concentrations that reaches a precision
close to the derived optimal bounds. Our results help rationalize the observed
ubiquity of receptor crosstalk in molecular sensing.

text: Dipolar coupling plays a fundamental role in the interaction between electrically
or magnetically polarized species such as magnetic atoms and dipolar molecules
in a gas or dipolar excitons in the solid state. Unlike Coulomb or contactlike
interactions found in many atomic, molecular, and condensed-matter systems, this
interaction is long-ranged and highly anisotropic, as it changes from repulsive
to attractive depending on the relative positions and orientation of the dipoles.
Because of this unique property, many exotic, symmetry-breaking collective states
have been recently predicted for cold dipolar gases, but only a few have been
experimentally detected and only in dilute atomic dipolar Bose-Einstein condensates.
Here, we report on the first observation of attractive dipolar coupling between
excitonic dipoles using a new design of stacked semiconductor bilayers. We show
that the presence of a dipolar exciton fluid in one bilayer modifies the spatial
distribution and increases the binding energy of excitonic dipoles in a vertically
remote layer. The binding energy changes are explained using a many-body polaron
model describing the deformation of the exciton cloud due to its interaction with
a remote dipolar exciton. The surprising nonmonotonic dependence on the cloud
density indicates the important role of dipolar correlations, which is unique
to dense, strongly interacting dipolar solid-state systems. Our concept provides
a route for the realization of dipolar lattices with strong anisotropic interactions
in semiconductor systems, which open the way for the observation of theoretically
predicted new and exotic collective phases, as well as for engineering and sensing
their collective excitations.

text: Chains of superconducting circuit devices provide a natural platform for studies
of synthetic bosonic quantum matter. Motivated by the recent experimental progress
in realizing disordered and interacting chains of superconducting transmon devices,
we study the bosonic many-body localization phase transition using the methods
of exact diagonalization as well as matrix product state dynamics. We estimate
the location of transition separating the ergodic and the many-body localized
phases as a function of the disorder strength and the many-body on-site interaction
strength. The main difference between the bosonic model realized by superconducting
circuits and similar fermionic model is that the effect of the on-site interaction
is stronger due to the possibility of multiple excitations occupying the same
site. The phase transition is found to be robust upon including longer-range hopping
and interaction terms present in the experiments. Furthermore, we calculate experimentally
relevant local observables and show that their temporal fluctuations can be used
to distinguish between the dynamics of Anderson insulator, many-body localization,
and delocalized phases. While we consider unitary dynamics, neglecting the effects
of dissipation, decoherence, and measurement back action, the timescales on which
the dynamics is unitary are sufficient for observation of characteristic dynamics
in the many-body localized phase. Moreover, the experimentally available disorder
strength and interactions allow for tuning the many-body localization phase transition,
thus making the arrays of superconducting circuit devices a promising platform
for exploring localization physics and phase transition.

text: Recent scanning tunneling microscopy experiments in NbN thin disordered superconducting
films found an emergent inhomogeneity at the scale of tens of nanometers. This
inhomogeneity is mirrored by an apparent dimensional crossover in the paraconductivity
measured in transport above the superconducting critical temperature Tc. This
behavior was interpreted in terms of an anomalous diffusion of fluctuating Cooper
pairs that display a quasiconfinement (i.e., a slowing down of their diffusive
dynamics) on length scales shorter than the inhomogeneity identified by tunneling
experiments. Here, we assume this anomalous diffusive behavior of fluctuating
Cooper pairs and calculate the effect of these fluctuations on the electron density
of states above Tc. We find that the density of states is substantially suppressed
up to temperatures well above Tc. This behavior, which is closely reminiscent
of a pseudogap, only arises from the anomalous diffusion of fluctuating Cooper
pairs in the absence of stable preformed pairs, setting the stage for an intermediate
behavior between the two common paradigms in the superconducting-insulator transition,
namely, the localization of Cooper pairs (the so-called bosonic scenario) and
the breaking of Cooper pairs into unpaired electrons due to strong disorder (the
so-called fermionic scenario).

text: "Recent studies suggest that unstable recurrent solutions of the Navier-Stokes
equation provide new insights\r\ninto dynamics of turbulent flows. In this study,
we compute an extensive network of dynamical connections\r\nbetween such solutions
in a weakly turbulent quasi-two-dimensional Kolmogorov flow that lies in the inversion
symmetric subspace. In particular, we find numerous isolated heteroclinic connections
between different\r\ntypes of solutions—equilibria, periodic, and quasiperiodic
orbits—as well as continua of connections forming\r\nhigher-dimensional connecting
manifolds. We also compute a homoclinic connection of a periodic orbit and\r\nprovide
strong evidence that the associated homoclinic tangle forms the chaotic repeller
that underpins transient\r\nturbulence in the symmetric subspace."

text: We modify the "floating crystal" trial state for the classical homogeneous
electron gas (also known as jellium), in order to suppress the boundary charge
fluctuations that are known to lead to a macroscopic increase of the energy. The
argument is to melt a thin layer of the crystal close to the boundary and consequently
replace it by an incompressible fluid. With the aid of this trial state we show
that three different definitions of the ground-state energy of jellium coincide.
In the first point of view the electrons are placed in a neutralizing uniform
background. In the second definition there is no background but the electrons
are submitted to the constraint that their density is constant, as is appropriate
in density functional theory. Finally, in the third system each electron interacts
with a periodic image of itself; that is, periodic boundary conditions are imposed
on the interaction potential.

text: End-to-end correlated bound states are investigated in superconductor-semiconductor
hybrid nanowires at zero magnetic field. Peaks in subgap conductance are independently
identified from each wire end, and a cross-correlation function is computed that
counts end-to-end coincidences, averaging over thousands of subgap features. Strong
correlations in a short, 300-nm device are reduced by a factor of 4 in a long,
900-nm device. In addition, subgap conductance distributions are investigated,
and correlations between the left and right distributions are identified based
on their mutual information.

text: We introduce a simple, exactly solvable strong-randomness renormalization
group (RG) model for the many-body localization (MBL) transition in one dimension.
Our approach relies on a family of RG flows parametrized by the asymmetry between
thermal and localized phases. We identify the physical MBL transition in the limit
of maximal asymmetry, reflecting the instability of MBL against rare thermal inclusions.
We find a critical point that is localized with power-law distributed thermal
inclusions. The typical size of critical inclusions remains finite at the transition,
while the average size is logarithmically diverging. We propose a two-parameter
scaling theory for the many-body localization transition that falls into the Kosterlitz-Thouless
universality class, with the MBL phase corresponding to a stable line of fixed
points with multifractal behavior.

text: We consider a two-component Bose gas in two dimensions at a low temperature
with short-range repulsive interaction. In the coexistence phase where both components
are superfluid, interspecies interactions induce a nondissipative drag between
the two superfluid flows (Andreev-Bashkin effect). We show that this behavior
leads to a modification of the usual Berezinskii-Kosterlitz-Thouless (BKT) transition
in two dimensions. We extend the renormalization of the superfluid densities at
finite temperature using the renormalization-group approach and find that the
vortices of one component have a large influence on the superfluid properties
of the other, mediated by the nondissipative drag. The extended BKT flow equations indicate that the occurrence of the
vortex unbinding transition in one of the components can induce the breakdown
of superfluidity also in the other, leading to a locking phenomenon for the critical
temperatures of the two gases.

text: The angular momentum of molecules, or, equivalently, their rotation in three-dimensional
space, is ideally suited for quantum control. Molecular angular momentum is naturally
quantized, time evolution is governed by a well-known Hamiltonian with only a
few accurately known parameters, and transitions between rotational levels can
be driven by external fields from various parts of the electromagnetic spectrum.
Control over the rotational motion can be exerted in one-, two-, and many-body
scenarios, thereby allowing one to probe Anderson localization, target stereoselectivity
of bimolecular reactions, or encode quantum information to name just a few examples.
The corresponding approaches to quantum control are pursued within separate, and
typically disjoint, subfields of physics, including ultrafast science, cold collisions,
ultracold gases, quantum information science, and condensed-matter physics. It
is the purpose of this review to present the various control phenomena, which
all rely on the same underlying physics, within a unified framework. To this end,
recall the Hamiltonian for free rotations, assuming the rigid rotor approximation
to be valid, and summarize the different ways for a rotor to interact with external
electromagnetic fields. These interactions can be exploited for control—from achieving
alignment, orientation, or laser cooling in a one-body framework, steering bimolecular
collisions, or realizing a quantum computer or quantum simulator in the many-body
setting.

text: We derive a tight lower bound on equivocation (conditional entropy), or equivalently
a tight upper bound on mutual information between a signal variable and channel
outputs. The bound is in terms of the joint distribution of the signals and maximum
a posteriori decodes (most probable signals given channel output). As part of
our derivation, we describe the key properties of the distribution of signals,
channel outputs and decodes, that minimizes equivocation and maximizes mutual
information. This work addresses a problem in data analysis, where mutual information
between signals and decodes is sometimes used to lower bound the mutual information
between signals and channel outputs. Our result provides a corresponding upper
bound.

text: "We design fast deterministic algorithms for distance computation in the CONGESTED
CLIQUE model. Our key contributions include:\r\n\r\n - A (2+ε)-approximation for
all-pairs shortest paths problem in O(log²n / ε) rounds on unweighted undirected
graphs. With a small additional additive factor, this also applies for weighted
graphs. This is the first sub-polynomial constant-factor approximation for APSP
in this model.\r\n - A (1+ε)-approximation for multi-source shortest paths problem
from O(√n) sources in O(log² n / ε) rounds on weighted undirected graphs. This
is the first sub-polynomial algorithm obtaining this approximation for a set of
sources of polynomial size.\r\n\r\nOur main techniques are new distance tools
that are obtained via improved algorithms for sparse matrix multiplication, which
we leverage to construct efficient hopsets and shortest paths. Furthermore, our
techniques extend to additional distance problems for which we improve upon the
state-of-the-art, including diameter approximation, and an exact single-source
shortest paths algorithm for weighted undirected graphs in Õ(n^{1/6}) rounds."
