Current Correlations and Conductivity in SYK-Like Systems: An Analytical Study
Rishabh Jha, Stefan Kehrein, Jan C. Louw
We present a functional-based approach to compute thermal expectation values for actions expressed in the formalism, applicable to any time sequence ordering. Utilizing this…

Bosonic representation of a Lipkin-Meshkov-Glick model with Markovian dissipation
Jan C. Louw, Michael Kastner, Johannes N. Kriel
We study the dynamics of a Lipkin-Meshkov-Glick model in the presence of Markovian dissipation, with a focus on late-time dynamics and the approach to thermal equilibrium. Making u…

Thermalization of a Lipkin-Meshkov-Glick model coupled to a bosonic bath
Jan C. Louw, Johannes N. Kriel, Michael Kastner
We derive a Lindblad master equation that approximates the dynamics of a Lipkin-Meshkov-Glick (LMG) model weakly coupled to a bosonic bath. By studying the time evolution of operat…
