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.
