Quantum Chaos and Coherence: Random Parametric Quantum Channels [PDF]
Quantum, 2023 The survival probability of an initial Coherent Gibbs State (CGS) is a natural extension of the Spectral Form Factor (SFF) to open quantum systems. To quantify the interplay between quantum chaos and decoherence away from the semi-classical limit, we ...

Quantifying Quantum Chaos through Microcanonical Distributions of Entanglement [PDF]
Physical Review X, 2023 A characteristic feature of “quantum chaotic” systems is that their eigenspectra and eigenstates display universal statistical properties described by random matrix theory (RMT). However, eigenstates of local systems also encode structure beyond RMT.

Quantum chaos without false positives [PDF]
Physical Review D, 2023 Out-of-time-order correlators are widely used as an indicator of quantum chaos, but give false-positive quantum Lyapunov exponents for integrable systems with isolated saddle points.

Statistics of phase space localization measures and quantum chaos in the kicked top model. [PDF]
Physical Review E, 2023 Quantum chaos plays a significant role in understanding several important questions of recent theoretical and experimental studies. Here, by focusing on the localization properties of eigenstates in phase space (by means of Husimi functions), we explore ...

Quantum chaos, integrability, and late times in the Krylov basis. [PDF]
Physical Review E, 2023 Quantum chaotic systems are conjectured to display a spectrum whose fine-grained features (gaps and correlations) are well described by random matrix theory (RMT). We propose and develop a complementary version of this conjecture: quantum chaotic systems

Out-of-time-order correlations and quantum chaos [PDF]
Scholarpedia, 2022 Quantum Chaos has originally emerged as the field which studies how the properties of classical chaotic systems arise in their quantum counterparts. The growing interest in quantum many-body systems, with no obvious classical meaning has led to consider ...

Quantum–Classical Mechanics and the Franck–Condon Principle
Computer Sciences & Mathematics Forum, 2023 Quantum–classical mechanics and the Franck–Condon principle related to quantum mechanics are discussed as two alternative theoretical approaches to molecular optical spectroscopy.

Spectral Statistics of Non-Hermitian Matrices and Dissipative Quantum Chaos. [PDF]
Physical Review Letters, 2021 We propose a measure, which we call the dissipative spectral form factor (DSFF), to characterize the spectral statistics of non-Hermitian (and nonunitary) matrices.

Probing Many-Body Quantum Chaos with Quantum Simulators [PDF]
Physical Review X, 2021 The spectral form factor (SFF), characterizing statistics of energy eigenvalues, is a key diagnostic of many-body quantum chaos. In addition, partial spectral form factors (PSFFs) can be defined which refer to subsystems of the many-body system.
