论文摘要
我们探讨了在石墨烯片附近的两级原子中光学双重性的出现和主动控制。我们的理论结合了光学驱动的原子的自我交流及其与电磁真空模式的耦合，这两种模式都对石墨烯中的电气可调的间跨过渡阈值敏感。我们表明，电流的双重性和滞后性可以在原子发出的光的强度，光谱和量子统计中表现出来，该光经历了对稳态的关键降低。光学驱动的原子 - 磷酸相互作用构成了一个平台，用于在量子相干控制和原子物理学中积极控制驱动的原子系统。
We explore the emergence and active control of optical bistability in a two-level atom near a graphene sheet. Our theory incorporates self-interaction of the optically-driven atom and its coupling to electromagnetic vacuum modes, both of which are sensitive to the electrically-tunable interband transition threshold in graphene. We show that electro-optical bistability and hysteresis can manifest in the intensity, spectrum, and quantum statistics of the light emitted by the atom, which undergoes critical slow-down to steady-state. The optically-driven atom-graphene interaction constitutes a platform for active control of driven atomic systems in quantum coherent control and atomic physics.
