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.

Quantum Chaos & Quantum Computers
, 2000 The standard generic quantum computer model is studied analytically and numerically and the border for emergence of quantum chaos, induced by imperfections and residual inter-qubit couplings, is determined.

Quantum Instantons and Quantum Chaos [PDF]
Physics Letters A, 2001 Based on a closed form expression for the path integral of quantum transition amplitudes, we suggest rigorous definitions of both, quantum instantons and quantum chaos.

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 ...

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 ...
