Query: Enhancing self-discharging process with disordered quantum batteries   The self-discharging of quantum batteries is a process in which the stored
charge is lost due to decoherence acting on the system. In this paper we show
how to enhance the performance of such a devices against loss of ergotropy by
introducing disorder in the local field acting on each cell. To this end, we
explore quantum sources to store ergotropy and disorder strong enough to
promotes a significant enhancement of the battery performance. Our results
suggest that by applying an disorder strong enough, the spontaneous decay of
the system leads to a creasing of the free ergotropy of the battery, as defined
from the free Hamiltonian of the system, reaching values bigger than the
initial amount of stored ergotropy. We call this spontaneous charging of the
battery, since it is a result of the combined action of spontaneous emission
and disorder effects. In addition, we also show how disorder effects allow us
to enhance the half-life of the battery. Our study opens perspective to further
investigation of the performance of quantum batteries that explore disorder and
many-body effects.
