• Abstract: Quantum resonance arising whenever the ratio of the intrinsic system frequency to the driving frequency becomes a rational number has been demonstrated to generate super-linear entanglement, enhance transport, quantum metrology performance and communication. Here, we demonstrate that quantum resonance can also serve as a powerful resource for quantum batteries. We model the batteries as free rotors charged via a kicked protocol. When the individual batteries are at resonance, we show both analytically and numerically that charging power increases linearly with time while efficiency (defined as the fraction of stored energy that can be extracted) remains near unity despite strong entanglement generation. Furthermore, we demonstrate that this enhanced performance persists at higher-order resonances. Demonstrating the universality of this mechanism, we show that similar enhancements arise in the interacting kicked top model, and briefly note the feasibility of its experimental realization. In a broader context, resonant charging holds significant implications for energy storage, quantum computational resources, and quantum thermodynamics.

• Hyperbolic enhancement of a quantum battery [0.0]
  We show how one can circumvent the problem of energy loss by proposing a quantum battery model. Namely, charging the battery quadratically with a short temporal pulse induces a hyperbolic enhancement in the stored energy. We show that when the driving is strong enough the useful work which can be extracted from the quantum battery, that is the ergotropy, is exactly equal to the stored energy.

The ratchet effect is achieved in the quantum control model with dissipation and sink, where the Hamiltonian depends on vibrations in the energy difference synchronized with transitions between energy levels. Amplitude and frequency of the oscillating vibron together with the dephasing rate are the parameters of the quantum ratchet which determine its efficiency.

• Quantum advantage in charging cavity and spin batteries by repeated interactions [0.0]
  Recently, an unconditional advantage has been demonstrated for the process of charging of a quantum battery in a collisional model. We consider a model where the battery is modeled by a quantum harmonic oscillator or a large spin, charged via repeated interactions with a stream of non-equilibrium qubit units. For both setups, we show that a quantum protocol can significantly outperform the most general adaptive classical schemes.
