Using dark states to charge and stabilise open quantum batteries
arXiv:2002.10044 · doi:10.1103/PhysRevApplied.14.024092
Abstract
We introduce an open quantum battery protocol using dark states to achieve both superextensive capacity and power density, with non-interacting spins coupled to a reservoir. Further, our power density actually scales with the of number of spins in the battery. We show that the enhanced capacity and power is correlated with entanglement. Whilst connected to the charger, the charged state of the battery is a steady state, stabilized through quantum interference in the open system.
