abstract

The development of fast and efficient quantum batteries is crucial for the prospects of quantum technologies. We show that both requirements are accomplished in the paradigmatic model of a harmonic oscillator strongly coupled to a highly non-Markovian thermal reservoir. At short times, a dynamical blockade of the reservoir prevents the leakage of energy towards its degrees of freedom, promoting a significant accumulation of energy in the battery with high efficiency. The possibility of implementing these conditions in $LC$ quantum circuits opens up new avenues for solid-state quantum batteries.

  1. Charging a Dimerized Quantum XY Chain

    For a dimerized XY chain used as a quantum battery, the asymptotic stored energy rises, then slowly increases, then falls as charging parameters cross the two quantum critical lines.
