Quantum Batteries and Quantum Energy Control

Quantum batteries use quantum degrees of freedom to store and transfer energy. We study how collective interactions, topology, and non-Hermitian dynamics affect charging power, stored energy, and long-time performance.

Our PT-symmetric SSH quantum battery study (2026) investigates the interplay of topology, exceptional points, and charging dynamics. Ongoing research extends these questions to light-matter battery models and energy extraction, distinguishing stored energy from extractable work and accounting for the physical charging protocol.
