Dynamical View of Quantum Thermodynamics

Quantum thermodynamics addresses the emergence of thermodynamical laws from quantum mechanics. The viewpoint advocated is based on the intimate connection of quantum thermodynamics with the theory of open quantum systems. Quantum mechanics inserts dynamics into thermodynamics giving a sound foundation to nite-time-thermodynamics. The emergence of the 0-law I-law
II-law and III-law of thermodynamics from quantum considerations will be presented through examples. I will show that the 3-level laser is equivalent to Carnot engine. I will reverse the engine and obtain a quantum refrigerator. Different models of quantum refrigerators and their optimisation will be discussed. A heat-driven refrigerator (absorption refrigerator) is compared to a power-driven
refrigerator related to laser cooling. This will lead to a dynamical version of the III-law of thermo dynamics limiting the rate of cooling when the absolute zero is approached. Finally I will present a quantum version of the Otto engine which allows to identify the quantum origin of friction in the failure of adiabatic following.
