Title: Dynamical View of Quantum Thermodynamics: Insight from Heat Engines

Abstract:

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 
finite-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.

I will show that various engine types are thermodynamically equivalent 
in the quantum limit

of small engine action. I will address the question why we find heat 
exchangers and flywheels

in quantum engines. I will present a molecular model of a heat rectifier 
and a heat pump in a

non-Markovian and strong coupling regime [? ].
