• Abstract: We show that a micromaser is an excellent model of quantum battery. A highly excited, pure, and effectively steady state of the cavity mode, charged by coherent qubits, can be achieved, also in the ultrastrong coupling regime of field-matter interaction. Stability of these appealing features against loss of coherence of the qubits and the effect of counter-rotating terms in the interaction Hamiltonian are also discussed.

  We report on a solid-state hybrid system capable of coherent microwave quantum amplification and oscillation at X band via the masing process at room temperature. By incorporating external driving and active dissipation control into the hybrid system, we achieve efficient tuning of the maser emission characteristics at around 9.4 GHz. Our work highlights opportunities for optimizing emerging solid-state masers for quantum information processing and communication.

• Strong mechanical squeezing in a microcavity with double quantum wells [0.0]
  In a hybrid quantum system composed of two quantum wells placed inside a cavity with a moving end mirror pumped by bichromatic coherent light, we address the formation of squeezed states of a mechanical resonator. We show that the robustness of this squeezing against thermal fluctuations is important for practical applications of such systems.

  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. 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.
