- Abstract summary: We investigate the charging and discharging dynamics of a three-level counterdiabatic stimulated Raman adiabatic passage quantum battery.
The scheme can significantly speed up the charging and discharging processes of a three-level quantum battery.
We explore the effect of both the amplitude and the delay time of driving fields on the performances of the quantum battery.

- Abstract: Quantum batteries are energy storage devices that satisfy quantum mechanical
principles. How to improve the battery's performance such as stored energy and
power is a crucial element in the quantum battery. Here, we investigate the
charging and discharging dynamics of a three-level counterdiabatic stimulated
Raman adiabatic passage quantum battery via shortcuts to adiabaticity, which
can compensate for undesired transitions to realize a fast adiabatic evolution
through the application of an additional control field to an initial
Hamiltonian. The scheme can significantly speed up the charging and discharging
processes of a three-level quantum battery and obtain more stored energy and
higher power compared with the original stimulated Raman adiabatic passage. We
explore the effect of both the amplitude and the delay time of driving fields
on the performances of the quantum battery. Possible experimental
implementation in superconducting circuit and nitrogen-vacancy center is also
discussed.
