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 ...

Symmetry of Open Quantum Systems: Classification of Dissipative Quantum Chaos [PDF]
PRX Quantum, 2022 We develop a theory of symmetry in open quantum systems. Using the operator-state mapping, we characterize symmetry of Liouvillian superoperators for the open quantum dynamics by symmetry of operators in the double Hilbert space and apply the 38-fold ...

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

Many-body quantum chaos and dual-unitarity round-a-face. [PDF]
Chaos, 2021 We propose a new type of locally interacting quantum circuits-quantum cellular automata-that are generated by unitary interactions round-a-face (IRF). Specifically, we discuss a set (or manifold) of dual-unitary IRFs with local Hilbert space dimension d [

Quantum irreversibility and chaos [PDF]
Physical Review Letters, 1991 Abstract Herein we establish a relation between quantum irreversibility and the chaotic semi-classical solutions for a spin-boson Hamiltonian system. We obtain quantum averages by numerically integrating the appropriate Liouville-Von Neumann equations of motion and find these averages to be less erratic than the corresponding chaotic ...

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 ...

Spectral Filtering Induced by Non-Hermitian Evolution with Balanced Gain and Loss: Enhancing Quantum Chaos. [PDF]
Physical Review Letters, 2021 The dynamical signatures of quantum chaos in an isolated system are captured by the spectral form factor, which exhibits as a function of time a dip, a ramp, and a plateau, with the ramp being governed by the correlations in the level spacing ...

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 ...
