Periodically driven many-body quantum battery

We explore the charging of a quantum battery based on spin systems through periodic modulation of a transverse-field-like Ising Hamiltonian. In the integrable limit, we find that resonance tunneling can lead to a higher transfer of energy to the battery and better stability of the stored energy at specific drive frequencies. When the integrability is broken in the presence of an additional longitudinal field, we find that the effective Floquet Hamiltonian contains terms which may lead to a global charging of the battery. However, we do not find any quantum advantage in the charging power, thus demonstrating that global charging is only a necessary and not sufficient condition for achieving quantum advantage.

Automated summary

In this study, we investigate the charging of a quantum battery by modulating the Hamiltonian and find that resonance tunneling at specific drive frequencies can enhance energy transfer and improve energy storage stability. Breaking the integrability allows for global charging of the battery, but there is no quantum advantage in terms of charging power.
