Work extraction from a quantum battery charged through an array of coupled cavities
I. Beder, D. Ferraro, P. A. Brandão
We investigate the problem of work extraction from a cavity-based quantum battery that is remotely charged via a transmission line composed of an array of coupled single-mode cavit…
