Universal quench dynamics of lattice fermion Yukawa Sachdev-Ye-Kitaev model
Haixin Qiu, Stefan Kehrein
We study the quantum quench of the Yukawa Sachdev-Ye-Kitaev model and one of its lattice extensions with fermions and one boson. Several equilibrium properties are computed for…

Page Curve and Entanglement Dynamics in an Interacting Fermionic Chain
Rishabh Jha, Salvatore R. Manmana, Stefan Kehrein
Generic non-equilibrium many-body systems display a linear growth of bipartite entanglement entropy in time, followed by a volume law saturation. In stark contrast, the Page curve…

Thermalization of a Closed Sachdev-Ye-Kitaev System in the Thermodynamic Limit
Santiago Salazar Jaramillo, Rishabh Jha, Stefan Kehrein
The question of thermalization of a closed quantum system is of central interest in non-equilibrium quantum many-body physics. Here we present one such study analyzing the dynamics…
