Nanocoolers
Abstract
We present a simple kinematic model of a non-equilibrium steady state device, which can operate either as a heat engine or as a refrigerator. The model is composed of two or more scattering channels where the motion is fully described by deterministic classical dynamics, which connect a pair of stochastic (infinite) heat and particle baths at unequal temperatures. We discuss precise kinematic conditions under which our model may approach Carnot's optimal efficiency in different situations.
