Fragmented ETH: Prethermalization, Timescales, and Ensemble Inequivalence
C. L. Sriram, Soumya Kanti Pal, Lea F. Santos
We investigate how finite quantum systems with strong long-range interactions approach thermal equilibrium. Nearly conserved quantities inherited from the fully connected limit fra…
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…
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…
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…
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…
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…
