Quantum kicked rotor and its variants: Chaos, localization and beyond

MS Santhanam, S Paul, JB Kannan - Physics Reports, 2022 - Elsevier
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 …

Multifractality and critical fluctuations at the Anderson transition

AD Mirlin, F Evers - Physical Review B, 2000 - APS
Critical fluctuations of wave functions and energy levels at the Anderson transition are
studied for the family of the power-law random banded matrix ensembles. It is shown that the …

Entanglement of midspectrum eigenstates of chaotic many-body systems: Reasons for deviation from random ensembles

M Haque, PA McClarty, IM Khaymovich - Physical Review E, 2022 - APS
Eigenstates of local many-body interacting systems that are far from spectral edges are
thought to be ergodic and close to being random states. This is consistent with the …

Multifractal dimensions for random matrices, chaotic quantum maps, and many-body systems

A Bäcker, M Haque, IM Khaymovich - Physical Review E, 2019 - APS
Multifractal dimensions allow for characterizing the localization properties of states in
complex quantum systems. For ergodic states the finite-size versions of fractal dimensions …

Level statistics across the many-body localization transition

P Sierant, J Zakrzewski - Physical Review B, 2019 - APS
Level statistics of systems that undergo many-body localization transition are studied. An
analysis of the gap ratio statistics from the perspective of inter-and intrasample randomness …

Statistics of resonances and delay times in random media: beyond random matrix theory

T Kottos - Journal of Physics A: Mathematical and General, 2005 - iopscience.iop.org
We review recent developments in quantum scattering from mesoscopic systems. Various
spatial geometries whose closed analogues show diffusive, localized or critical behaviour …

Enhanced phase-coherent multifractal two-dimensional superconductivity

B Fan, AM García-García - Physical Review B, 2020 - APS
We study the interplay of superconductivity and disorder by solving numerically the
Bogoliubov–de Gennes equations in a two-dimensional lattice of size 80× 80, which makes …

Superconductivity at the three-dimensional Anderson metal-insulator transition

B Fan, AM García-García - Physical Review B, 2020 - APS
We study a disordered weakly coupled superconductor around the Anderson transition by
solving numerically the Bogoliubov–de Gennes (BdG) equations in a three-dimensional …

Quasi-many-body localization of interacting fermions with long-range couplings

SJ Thomson, M Schiró - Physical Review Research, 2020 - APS
A number of experimental platforms for quantum simulations of disordered quantum matter,
from dipolar systems to trapped ions, involve degrees of freedom which are coupled by …

Reducing dynamical fluctuations and enforcing self-averaging by opening many-body quantum systems

I Vallejo-Fabila, AK Das, DA Zarate-Herrada… - Physical Review B, 2024 - APS
We investigate how the dynamical fluctuations of many-body quantum systems out of
equilibrium can be mitigated when they are opened to a dephasing environment. We …
