• Abstract: Quantum batteries have attracted significant attention as efficient quantum energy storage devices.In this work, we propose a nonlinear two-photon driving quantum battery model featuring nonreciprocal dynamics that enables a highly efficient unidirectional charging mechanism through environmental engineering. Using a Markovian master-equation approach, we derive analytical solutions for the system dynamics and identify the parameter regime required for dynamical equilibration. Our results reveal that increasing the driving strength enhances both energy conversion and storage efficiency, albeit at the cost of longer equilibration times. Compared with single-photon driving, the two-photon process exhibits a pronounced advantage in energy capacity and entropy regulation, which becomes more prominent under stronger driving. Under asymmetric dissipation, optimizing the system-bath coupling can further improve performance. The proposed model is experimentally feasible and can be implemented across multiple quantum platforms, including photonic systems, superconducting circuits, and magnonic devices.

• Ultrafast charging in a two-photon Dicke quantum battery [0.0]
  We consider a collection of two level systems, such as qubits, embedded into a microwave cavity as a promising candidate for the realization of high power quantum batteries. By solving a Dicke model with both single- and two-photon coupling we determine the range of parameters where the latter unconventional interaction dominates the dynamics of the system. It is shown that the charging process is progressively faster by increasing the coupling from the weak to the ultra-strong regime.
