标题： Heitler effect and resonance fluorescence in quantum magnonics

摘要： 我们考虑一个由量子比特和磁振子模式组成的耦合系统，其中量子比特被弱驱动。 我们证明，量子比特和磁振子的谱稳态响应除了由耦合分裂的两个边带外，还在驱动频率处显示出一个几乎无线宽的峰。 这一现象在强耦合和弱耦合下均存在，是原子物理中Heitler效应的模拟，并展示了构建相干磁振子源的途径。 显示英文摘要

摘要： We consider a coupled system of a qubit and a magnon mode in which the qubit is weakly driven. We demonstrate that the spectral steady-state responses of both the qubit and the magnon show, in addition to two sidebands split by the coupling, also a peak at the driving frequency with virtually zero linewidth. This phenomenon, which persists at both strong and weak coupling, is an analog of the Heitler effect in atomic physics, and shows the path towards building of coherent magnon sources.
