Charging batteries with quantum squeezing

Abstract

We present a scheme for the charging of a quantum battery based on the dynamics of an open quantum system undergoing coherent quantum squeezing and affected by an incoherent squeezed thermal bath. We show that quantum coherence, as instigated by the application of coherent squeezing, is key in the determination of the performance of the charging process, which is efficiency-enhanced at low environmental temperatures and under a strong squeezed driving.
