Observable- and state-selective prethermalization and bounds on prethermal lifetimes
C. L. Sriram, Soumya Kanti Pal, Lea F. Santos
Prethermalization describes long-lived intermediate regimes that precede equilibrium and can dominate experimentally accessible dynamics. Here, we show that a separation of spectra…
Fragmented ETH and Ensemble Inequivalence
C. L. Sriram, Soumya Kanti Pal, Lea F. Santos
We investigate thermalization in finite quantum systems with strong long-range interactions. Nearly conserved quantities inherited from the fully connected limit organize the Hilbe…
Dissipation as a Resource: Synchronization, Coherence Recovery, and Chaos Control
Debabrata Mondal, Lea F. Santos, S. Sinha
Dissipation is commonly regarded as an obstacle to quantum control, as it induces decoherence and irreversibility. Here we demonstrate that dissipation can instead be exploited as…
Semiclassical entanglement entropy for spin-field interaction
Matheus V. Scherer, Lea F. Santos, Alexandre D. Ribeiro
We study a general bipartite quantum system consisting of a spin interacting with a bosonic field, with the initial state prepared as the product of a spin coherent state and a can…
Universal spectral correlations in open Floquet systems with localized leaks
Edson M. Signor, Miguel A. Prado Reynoso, Bidhi Vijaywargia +2
We show that introducing a localized leak in Floquet systems with time-reversal symmetry leads to universal spectral correlations governed by the non-Hermitian symmetry class $\mat…
Fragmented eigenstate thermalization versus robust integrability in long-range models
Soumya Kanti Pal, Lea F Santos
Understanding the stability of integrability in many-body quantum systems is key to controlling dynamics and predicting thermalization. While the breakdown of integrability in shor…
Transient and steady-state chaos in dissipative quantum systems
Debabrata Mondal, Lea F. Santos, S. Sinha
Dissipative quantum chaos plays a central role in the characterization and control of information scrambling, non-unitary evolution, and thermalization, but it still lacks a precis…
Spectral form factor and energy correlations in banded random matrices
Adway Kumar Das, Anandamohan Ghosh, Lea F. Santos
Banded random matrices were introduced as a more realistic alternative to full random matrices for describing the spectral statistics of heavy nuclei. Initially considered by Wigne…
Breakdown of the Quantum Distinction of Regular and Chaotic Classical Dynamics in Dissipative Systems
David Villaseñor, Lea F. Santos, Pablo Barberis-Blostein
Quantum chaos has recently received increasing attention due to its relationship with experimental and theoretical studies of nonequilibrium quantum dynamics, thermalization, and t…
Classical and Quantum Properties of the Spin-Boson Dicke Model: Chaos, Localization, and Scarring
David Villaseñor, Saúl Pilatowsky-Cameo, Jorge Chávez-Carlos +4
This review article describes major developments associated with the Dicke model, from its introduction in the 1950s to explain the transition from a normal to a superradiant phase…
