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 …

Dynamical phase transitions in periodically driven Bardeen-Cooper-Schrieffer systems
