Effective Quantum Jarzynski estimator for embedded subsystems — •Jens Teifel and Günter Mahler — Universität Stuttgart, Germany

We consider a composite quantum system. An effective description for local observables, e.g. energy, will be used in order to analyze the behavior of a given subsystem. This local behavior (process) might arise from external driving via an explicitly time-dependent local Hamiltonian or due to the effect of the surrounding quantum systems (or a combination of both). If the investigated subsystem is in a thermal state, we call the total state partially thermalized. Starting from such states we explore the possibility to formulate Jarzynski relations for the respective subsystems.
