An autonomous thermal machine for amplification of coherence — •Juan MR Parrondo¹, Gonzalo Manzano², and Ralph Silva³ — ¹Universidad Complutense de Madrid (Spain) — ²IFISC (Spain) — ³Université de Genève (Switzerland)

A common belief is that any contact of a quantum system with thermal baths implies the vanishing of any coherence in the energy eigenbasis. Here we present a model that questions this idea: an autonomous quantum thermal machine that is capable of amplifying the coherence in a non-degenerate system by using only thermal resources. The model illustrates new possibilities of interconversion between energy, both work and heat, and coherence, and opens up new possibilities in the generation and manipulation of coherence by autonomous thermal machines.
