Quantum Field Thermal Machines

Recent years have enjoyed an overwhelming interest in quantum thermodynamics, a field of research aimed at understanding thermodynamic tasks performed the regime. Further progress, however, seems to be obstructed by lack experimental implementations thermal machines which effects play decisive role. In this work, we introduce blueprint machines, - once experimentally realized would fill gap. Even though concept QFM presented here is very general and can implemented any many body system that described theory. We provide detailed proposal how realize machine one-dimensional ultra-cold atomic gases, consists set modular operations giving rise piston. These then coupled sequentially baths, with innovation takes up role working fluid. particular, propose models for compression on use it as piston, coupling bath gives valve controlling heat flow. are derived within Bogoliubov theory, allows us study operational primitives numerically efficient way. By composing modelled design complete cycles shown enable cooling hence refrigerator. The active achieved way operate regimes where existing methods become ineffective. describe consequences operating level give outlook work serves road map explore open questions information, non-Markovian dynamics.
