论文摘要
我们考虑了量子电池的微敏模型,其中电池是腔体中电磁场的单个模式,通过与量子台的重复相互作用,它们以相同的非平衡状态进行了反复相互作用,所有这些模式都在相同的非平衡状态下,无论是不相互的还是连贯的,无论是由Jaynes-Cummmumms型号模拟的物质 - 磁场相互作用。我们表明,连贯的协议优于不一致的协议,因为对于模型参数的通用值可以实现有效的纯稳态。最后,我们用lindblad主方程描述的腔损失补充了上述碰撞模型。我们表明,在存储的能量,充电功率和稳态纯度方面,电池性能略有降低至中度耗散率。我们的结果表明,微型主体是可靠且可靠的量子电池,因此使其成为实验实现的有前途的模型。
We consider a micromaser model of a quantum battery, where the battery is a single mode of the electromagnetic field in a cavity, charged via repeated interactions with a stream of qubits, all prepared in the same non-equilibrium state, either incoherent or coherent, with the matter-field interaction modeled by the Jaynes-Cummings model. We show that the coherent protocol is superior to the incoherent one, in that an effective pure steady state is achieved for generic values of the model parameters. Finally, we supplement the above collision model with cavity losses, described by a Lindblad master equation. We show that battery performances, in terms of stored energy, charging power, and steady-state purity, are slightly degraded up to moderated dissipation rate. Our results show that micromasers are robust and reliable quantum batteries, thus making them a promising model for experimental implementations.
