Probing the edge between integrability and quantum chaos in interacting few-atom systems [PDF]
Quantum, 2021 Interacting quantum systems in the chaotic domain are at the core of various ongoing studies of many-body physics, ranging from the scrambling of quantum information to the onset of thermalization.

Adiabatic Eigenstate Deformations as a Sensitive Probe for Quantum Chaos [PDF]
Physical Review X, 2020 In the past decades, it was recognized that quantum chaos, which is essential for the emergence of statistical mechanics and thermodynamics, manifests itself in the effective description of the eigenstates of chaotic Hamiltonians through random matrix ...

Probing quantum chaos in multipartite systems [PDF]
Physical Review Research, 2022 Understanding the emergence of quantum chaos in multipartite systems is challenging in the presence of interactions. We show that the contribution of the subsystems to the global behavior can be revealed by probing the full counting statistics of the ...

Simulating quantum chaos on a quantum computer. [PDF]
Sci RepWe show that currently available noisy intermediate-scale quantum (NISQ) computers can be used for versatile quantum simulations of chaotic systems. We introduce a novel classical-quantum hybrid approachfor exploring the dynamics of the chaotic quantum kicked top (QKT) on a universal quantum computer.

Quantum coherence as a signature of chaos
Physical Review Research, 2021 We establish a rigorous connection between quantum coherence and quantum chaos by employing coherence measures originating from the resource theory framework as a diagnostic tool for quantum chaos.

Quantum biology on the edge of quantum chaos. [PDF]
PLoS One, 2014 We give a new explanation for why some biological systems can stay quantum coherent for long times at room temperatures, one of the fundamental puzzles of quantum biology. We show that systems with the right level of complexity between chaos and regularity can increase their coherence time by orders of magnitude.

About the Concept of Quantum Chaos [PDF]
Entropy, 2017 The research on quantum chaos finds its roots in the study of the spectrum of complex nuclei in the 1950s and the pioneering experiments in microwave billiards in the 1970s. Since then, a large number of new results was produced.

Genuine quantum scars in many-body spin systems [PDF]
Nature CommunicationsChaos makes isolated systems of many interacting particles quickly thermalize and forget about their past. Here, we show that quantum mechanics hinders chaos in many-body systems: although the quantum eigenstates are thermal and strongly entangled ...

Quantum chaos and the complexity of spread of states [PDF]
Physical Review D, 2022 We propose a measure of quantum state complexity defined by minimizing the spread of the wave-function over all choices of basis. Our measure is controlled by the"survival amplitude"for a state to remain unchanged, and can be efficiently computed in ...
