Geometric phase in dissipative quantum batteries

Year: 2025

Type: article

Abstract: We study the geometric phase accumulated during non-adiabatic charging of different driven open quantum systems serving as quantum battery models. We provide a full numerical analysis of dynamics under different type of noises typically reported in superconducting circuits implementations. We complement the study with analytic results derived in the limiting case of no noise (i.e. isolated systems). We compute the non-unitary geometric phase acquired by the quantum batteries during the transition and show that there is a direct relation between the accumulated geometric phase and the integral of the stored energy during the transition. Finally, we perform the same analysis on a bipartite quantum battery that relies on a dephased charger and found similar results. Our theoretical findings are within experimental reach using state-of-the-art techniques.
