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.
