Sharp Page transitions in generic Hamiltonian dynamics
Lauren H. Li, Stefan Kehrein, Sarang Gopalakrishnan
We consider the entanglement dynamics of a subsystem initialized in a pure state at high energy density (corresponding to negative temperature) and coupled to a cold bath. The subs…
Resonant level model coupled to a Sachdev-Ye-Kitaev bath
Anastasia Enckell, Stefan Kehrein
We investigate the non-equilibrium dynamics of a resonant level model coupled to a strongly interacting electron bath modeled by a Sachdev-Ye-Kitaev (SYK) model. Different from the…
Rate Function Modelling of Quantum Many-Body Adiabaticity
Vibhu Mishra, Salvatore Manmana, Stefan Kehrein
The quantum adiabatic theorem is a fundamental result in quantum mechanics, with a multitude of applications, both theoretical and practical. Here, we investigate the dynamics of a…
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…
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…
