Quantum confinement and surface effects (SEs) dramatically modify most solid state
phenomena as one approaches the nanometer scale, and superconductivity is no …

We study a one-dimensional XXZ spin chain in a random field on the metallic side of the
many-body localization transition by level statistics. For a fixed interaction, and intermediate …

In a zero-dimensional superconductor, quantum size effects,(QSE) not only set the limit to
superconductivity, but are also at the heart of new phenomena such as shell effects, which …

We experimentally test the universality of the Anderson three dimensional metal-insulator
transition, using a quasiperiodic atomic kicked rotor. Nine sets of parameters controlling the …

The development of the fundamental superconducting (SC) energy scales—the SC energy
gap Δ and the superfluid stiffness J—of granular aluminum, ie, thin films composed of …

Using a cold atomic gas exposed to laser pulses—a realization of the chaotic quasiperiodic
kicked rotor with three incommensurate frequencies—we study experimentally and …

We propose a generalization of multifractal analysis that is applicable to the critical regime of
the Anderson localization-delocalization transition. The approach reveals that the behavior …

In this paper we present a thorough study of transport, spectral, and wave-function
properties at the Anderson localization critical point in spatial dimensions d= 3, 4, 5, 6. Our …

Eigenstate multifractality is a distinctive feature of noninteracting disordered metals close to
a metal–insulator transition, whose properties are expected to extend to superconductivity …

We study a disordered weakly coupled superconductor around the Anderson transition by
solving numerically the Bogoliubov–de Gennes (BdG) equations in a three-dimensional …
