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 ...

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 ...

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 ...

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.

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 ...

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–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.

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.
