Thermalization of non-Fermi-liquid electron-phonon systems: Hydrodynamic relaxation of the Yukawa-Sachdev-Ye-Kitaev model

H Hosseinabadi, SP Kelly, J Schmalian, J Marino - Physical Review B, 2023 - APS
We study thermalization dynamics in a fermion-phonon variant of the Sachdev-Ye-Kitaev
model coupled to an external cold thermal bath of harmonic oscillators. We find that …

Entanglement transitions in SU (1, 1) quantum dynamics: applications to Bose-Einstein condensates and periodically driven coupled oscillators

HH Li, PY Chang - arXiv preprint arXiv:2405.12558, 2024 - arxiv.org
We study the entanglement properties in non-equilibrium quantum systems with the SU (1,
1) structure. Through M\" obius transformation, we map the dynamics of these systems …
