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…
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…
Scaling behavior of interactions in a modular quantum system and the existence of local temperature
M. Hartmann, J. Gemmer, G. Mahler +1
We consider a quantum system of fixed size consisting of a regular chain of -level subsystems, where is finite. Forming groups of subsystems each, we show that the stren…
Relaxation into equilibrium under pure Schrödinger dynamics
P. Borowski, J. Gemmer, G. Mahler
We consider bipartite quantum systems that are described completely by a state vector and the fully deterministic Schrödinger equation. Under weak constraints and without…
On the concept of pressure in quantum mechanics
P. Borowski, J. Gemmer, G. Mahler
Heat and work are fundamental concepts for thermodynamical systems. When these are scaled down to the quantum level they require appropriate embeddings. Here we show that the depen…
