Experimental progress in atomic, molecular, and optical platforms in the last decade has
stimulated strong and broad interest in the quantum coherent dynamics of many long-range …

It is widely recognized that entanglement generation and dynamical chaos are intimately
related in semiclassical models via the process of decoherence. In this paper, we propose a …

Quantum many-body scars (QMBS) are exceptional energy eigenstates of quantum many-
body systems associated with violations of thermalization for special nonequilibrium initial …

Quantum metrology aims to measure physical quantities based on fundamental quantum
principles, enhancing measurement precision through resources like quantum …

Quantum chaos plays a significant role in understanding several important questions of
recent theoretical and experimental studies. Here, by focusing on the localization properties …

The properties of mixed eigenstates in a generic quantum system with a classical
counterpart that has mixed-type phase space, although important to understand several …

The out-of-time-ordered correlators (OTOCs) and the Loschmidt echo are two measures that
are now widely being explored to characterize sensitivity to perturbations and information …

We present the multifractal analysis of coherent states in kicked top model by expanding
them in the basis of Floquet operator eigenstates. We demonstrate the manifestation of …

Exactly solvable models that exhibit quantum signatures of classical chaos are both rare as
well as important—more so in view of the fact that the mechanisms for ergodic behavior and …

We present a method to calculate an upper bound on the generation of entanglement in any
spin system using the Fannes-Audenaert inequality for the von Neumann entropy. Our …
