Query: Charger-mediated energy transfer in exactly-solvable models for quantum
  batteries   We present a systematic analysis and classification of several models of
quantum batteries involving different combinations of two level systems and
quantum harmonic oscillators. In particular, we study energy transfer processes
from a given quantum system, termed charger, to another one, i.e. the proper
battery. In this setting, we analyze different figures of merit, including the
charging time, the maximum energy transfer, and the average charging power. The
role of coupling Hamiltonians which do not preserve the number of local
excitations in the charger-battery system is clarified by properly accounting
them in the global energy balance of the model.
