Kicked rotor is a paradigmatic model for classical and quantum chaos in time-dependent
Hamiltonian systems. More than fifty years since the introduction of this model, there is an …

Recent studies point towards nontriviality of the ergodic phase in systems exhibiting many‐
body localization (MBL), which shows subexponential relaxation of local observables …

Spectral statistics of disordered systems encode Thouless and Heisenberg timescales,
whose ratio determines whether the system is chaotic or localized. We show that the scaling …

We realize experimentally an atom-optics quantum-chaotic system, the quasiperiodic kicked
rotor, which is equivalent to a 3D disordered system that allows us to demonstrate the …

The quantum phase transition between the three dimensional Dirac semimetal and the
diffusive metal can be induced by increasing disorder. Taking the system of a disordered Z 2 …

We experimentally study anomalous diffusion of ultracold atoms in a one dimensional
polarization optical lattice. The atomic spatial distribution is recorded at different times and …

A theoretical analysis is given of the equation of motion method, due to Alben et al.[Phys.
Rev. B 12, 4090 (1975)], to compute the eigenvalue distribution (density of states) of very …

We report on a detailed analysis of the transport properties and superconducting critical
temperatures of boron-doped diamond films grown along the {100} direction. The system …

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 …

The disordered XXZ model is a prototype model of the many-body localization transition
(MBL). Despite numerous studies of this model, the available numerical evidence of …
