Minimal self-contained quadridot quantum refrigeration machine    [PDF]

Davide Venturelli, Rosario Fazio, Vittorio Giovannetti

We present a theoretical study of an electronic quantum refrigerator based on four quantum dots arranged in a square configuration, in contact with as many thermal reservoirs. We show that the system implements the basic minimal mechanism for acting as a self-contained quantum refrigerator, by demonstrating heat extraction from the coldest reservoir and the cooling of the nearby quantum-dot.
