• Abstract: Achieving quantum advantage in energy storage and power extraction is a primary objective in the design of quantum-based batteries. We explore how long-range (LR) interactions in conjunction with Floquet driving can improve the performance of quantum batteries, particularly when the battery is initialized in a fully polarized state. In particular, we exhibit that by optimizing the driving frequency, the maximum average power scales super extensively with system-size which is not achievable through next-nearest neighbor interactions or traditional unitary charging, thereby gaining genuine quantum advantage. We illustrate that the inclusion of either two-body or many-body interaction terms in the LR charging Hamiltonian leads to a scaling benefit. Furthermore, we discover that a super-linear scaling in power results from increasing the strength of interaction compared to the transverse magnetic field and the range of interaction with low fall-off rate, highlighting the advantageous role of long-range interactions in optimizing quantum battery charging.

  We propose an efficient charging quantum battery achieved by considering an extension Dicke model with dipole-dipole interaction and an external driving field. The maximum stored energy and maximum charging power are investigated by varying the number of atoms. In addition, the maximum charging power approximately satisfies a superlinear scaling relation $P_rm maxvarproptobeta Nalpha$, where the quantum advantage $alpha=1.6$ can be reached via optimizing the parameters.

• 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.

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.
