Signatures of Quantum Chaos of Rydberg-Dressed Bosons in a Triple-Well Potential
Atoms, 2023 We studied signatures of quantum chaos in dynamics of Rydberg-dressed bosonic atoms held in a one-dimensional triple-well potential. Long-range nearest-neighbor and next-nearest-neighbor interactions, induced by laser dressing atoms to strongly ...

Semiclassical roots of universality in many-body quantum chaos [PDF]
Journal of Physics A: Mathematical and Theoretical, 2022 Quantum chaos of many-body (MB) systems has been swiftly developing into a vibrant research area at the interface between various disciplines, ranging from statistical physics to condensed matter to quantum information and to cosmology.

Universality and its limits in non-Hermitian many-body quantum chaos using the Sachdev-Ye-Kitaev model [PDF]
Physical Review D, 2022 Spectral rigidity in Hermitian quantum chaotic systems signals the presence of dynamical universal features at timescales that can be much shorter than the Heisenberg time. We study the analog of this timescale in many-body non-Hermitian quantum chaos by

Quantum chaos in 2D gravity [PDF]
SciPost Physics, 2022 We present a quantitative and fully non-perturbative description of the ergodic phase of quantum chaos in the setting of two-dimensional gravity. To this end we describe the doubly non-perturbative completion of semiclassical 2D gravity in terms of its ...

Communications in Mathematical Sciences, 2018 We study the notion of quantum Kac's chaos which was implicitly introduced by Spohn and explicitly formulated by Gottlieb. We prove the analogue of a result of Sznitman which gives the equivalence of Kac's chaos to 2-chaoticity and to convergence of empirical measures.

From quantum chaos and eigenstate thermalization to statistical mechanics and thermodynamics [PDF]
, 2015 This review gives a pedagogical introduction to the eigenstate thermalization hypothesis (ETH), its basis, and its implications to statistical mechanics and thermodynamics. In the first part, ETH is introduced as a natural extension of ideas from quantum

Localization challenges quantum chaos in the finite two-dimensional Anderson model [PDF]
Physical review B, 2022 It is believed that the two-dimensional (2D) Anderson model exhibits localization for any nonzero disorder in the thermodynamic limit and it is also well known that the finite-size effects are considerable in the weak disorder limit.

Quantum Chaos in Time Series of Single Photons as a Superposition of Wave and Particle States
Photonics, 2021 We build a time series of single photons with quantum chaos statistics, using a version of the Grangier anti-correlation experiment. The criteria utilized to determine the presence of quantum chaos is the frame of the Fano factor and the power spectrum ...

Quantum Lyapunov exponents and complex spacing ratios: Two measures of dissipative quantum chaos. [PDF]
Chaos, 2021 The agenda of dissipative quantum chaos is to create a toolbox that would allow us to categorize open quantum systems into "chaotic" and "regular" ones. Two approaches to this categorization have been proposed recently.

Quantum Chirikov criterion: Two particles in a box as a toy model for a quantum gas
SciPost Physics, 2022 We consider a toy model for emergence of chaos in a quantum many-body short-range-interacting system: two one-dimensional hard-core particles in a box, with a small mass defect as a perturbation over an integrable system, the latter represented by two ...
