Title: Stochastic thermodynamics of a finite quantum system coupled to a heat bath
Authors: Heinz-J\"urgen Schmidt, J\"urgen Schnack and Jochen Gemmer
Abstract summary: We find that heat and entropy is flowing from the hot bath to the cold NLS. The Clausius relation between increase of entropy and transfer of heat divided by a suitable temperature assumes the form of two inequalities.

Abstract: We consider a situation where an $N$-level system (NLS) is coupled to a heat bath without being necessarily thermalized. For this situation we derive general Jarzinski-type equations and conclude that heat and entropy is flowing from the hot bath to the cold NLS and, vice versa, from the hot NLS to the cold bath. The Clausius relation between increase of entropy and transfer of heat divided by a suitable temperature assumes the form of two inequalities which have already been considered in the literature. Our approach is illustrated by an analytical example.

Thermodynamic Roles of Quantum Environments: From Heat Baths to Work Reservoirs [49.1574468325115]
Environments in quantum thermodynamics usually take the role of heat baths. We show that within the same model, the environment can take three different thermodynamic roles. The exact role of the environment is determined by the strength and structure of the coupling.

Pseudomode treatment of strong-coupling quantum thermodynamics [0.0]
The evaluation of thermodynamic quantities in strong-coupling regimes requires a nonperturbative knowledge of the bath dynamics. We derive expressions for heat, work, and average system-bath interaction energy that only involve the autocorrelation function of the bath. We show in particular that this method allows for an efficient numerical evaluation of thermodynamic quantities.

Qubit thermodynamics far from equilibrium: two perspectives about the nature of heat and work in the quantum regime [68.8204255655161]
We develop an alternative theoretical framework for the thermodynamic analysis of two-level systems. We observe the appearance of a new term of work, which represents the energy cost of rotating the Bloch vector in presence of the external field that defines the local Hamiltonian. In order to illustrate our findings we study, from both perspectives, matter-radiation interaction processes for two different systems.

An explicit expression for the temperature of an open two-level quantum system is obtained. This temperature coincides with the environment temperature if the system reaches thermal equilibrium with a heat reservoir. We show that within this theoretical framework the total entropy production can be partitioned into two contributions.
