Query: Quantum versus classical many-body batteries   Quantum batteries are quantum mechanical systems with many degrees of freedom
which can be used to store energy and that display fast charging. The physics
behind fast charging is still unclear. Is this just due to the collective
behavior of the underlying interacting many-body system or does it have its
roots in the quantum mechanical nature of the system itself? In this work we
address these questions by studying three examples of quantum-mechanical
many-body batteries with rigorous classical analogs. We find that the answer is
model dependent and, even within the same model, depends on the value of the
coupling constant that controls the interaction between the charger and the
battery itself.
