A minimal model of a quantum refrigerator (QR), i.e. a periodically phase-flipped two-level system permanently coupled to a finite-capacity bath (cold bath) and an infinite heat dump (hot bath), is introduced and used to investigate the cooling of the cold bath towards the absolute zero (T = 0). Remarkably, the temperature scaling of the cold-bath cooling rate reveals that it does not vanish as T → 0 for certain realistic quantized baths, e.g. phonons in strongly disordered media (fractons) or…

Quantum refrigerators and the third law of thermodynamics.
The rate of temperature decrease of a cooled quantum bath is studied as its temperature is reduced to absolute zero. The third law of thermodynamics is then quantified dynamically by evaluating the…
Quantum heat engines and refrigerators: continuous devices.
TLDR
The quantum tricycle, a device connected by three external leads to three heat reservoirs, is used as a template for engines and refrigerators, and all refrigerators as Tc→0 show universal behavior.
Features of Complexity
We examine the emergence of complexity in the interface between quantum and classical mechanics. By using the algorithmic complexity of Kolmogorov as our definition we can explore complexity of a…
Quantum Thermodynamics: A Dynamical Viewpoint
TLDR
The emergence of the 0-law, I- law, II-law and III-law of thermodynamics from quantum considerations is presented and it is claimed that inconsistency is the result of faulty analysis, pointing to flaws in approximations.
