Examination of classical simulations for Heisenberg-Langevin equations for spin-1/2
Scott D. Linz, Jochen Gemmer
A system of spins coupled to a bath is a traditional setup in open quantum systems. Through Heisenberg's equation, the spin dynamics can be modeled by a set of first-order differen…
Stochastic thermodynamics of a finite quantum system coupled to a heat bath
Heinz-Jürgen Schmidt, Jürgen Schnack, Jochen Gemmer
We consider a situation where an -level system (NLS) is coupled to a heat bath without being necessarily thermalized. For this situation we derive general Jarzinski-type equatio…
Necessity of eigenstate thermalization for equilibration towards unique expectation values when starting from generic initial states
Christian Bartsch, Jochen Gemmer
We investigate dynamical equilibration of expectation values in closed quantum systems for realistic non-equilibrium initial states. Thereby we find that the corresponding long tim…
Transient fluctuation theorem in closed quantum systems
Christian Bartsch, Jochen Gemmer
Our point of departure are the unitary dynamics of closed quantum systems as generated from the Schrödinger equation. We focus on a class of quantum models that typically exhibit r…
Quantum thermal equilibration from equipartition
A. V. Ponomarev, S. Denisov, J. Gemmer +1
The problem of mutual equilibration between two finite, identical quantum systems, A and B, prepared initially at different temperatures is elucidated. We show that the process of…
Heat conductivity in small quantum systems: Kubo formula in Liouville space
Mathias Michel, Jochen Gemmer, Guenter Mahler
We consider chains consisting of several identical subsystems weakly coupled by various types of next neighbor interactions. At both ends the chain is coupled to a respective heat…
