Autonomous thermal machine for amplification and control of energetic coherence — •Gonzalo Manzano^1,2, Ralph Silva³, and Juan M. R.

We present a model for an autonomous quantum thermal machine comprised by two qubits that is capable of amplifying the coherence in a non-degenerate system by using only thermal resources. This novel method of coherent control allows for the interconversion between energy, both work and heat, and coherence. This model opens up new possibilities in the generation and manipulation of coherence by autonomous thermal machines.
