Rabi问题的PT谱
PT spectroscopy of the Rabi problem
摘要：
我们研究了具有时间周期的、非厄米的、PT对称的微扰对具有两个（或几个）能级的系统的影响，并得到了它的相图作为微扰强度和频率的函数。我们证明，当扰动频率接近系统共振之一时，即使是一个非常小的扰动导致PT对称性破缺。我们还发现一个恢复PT对称相位在高频率，并在中等扰动强度，我们发现多个频率窗口，PT对称性被打破和恢复。我们的研究结果意味着，PT对称拉比问题显示出令人惊讶的丰富的现象，缺乏在其厄米或静态的同行。
英文摘要：
We investigate the effects of a time-periodic, non-hermitian, PT-symmetric perturbation on a system with two (or few) levels, and obtain its phase diagram as a function of the perturbation strength and frequency. We demonstrate that when the perturbation frequency is close to one of the system resonances, even a vanishingly small perturbation leads to PT symmetry breaking. We also find a restored PT-symmetric phase at high frequencies, and at moderate perturbation strengths, we find multiple frequency windows where PT-symmetry is broken and restored. Our results imply that the PT-symmetric Rabi problem shows surprisingly rich phenomena absent in its hermitian or static counterparts.
