论文摘要
提出了一种量子传感方案，以证明圆形极化的Rydberg原子的运动引起的手性。为此，rydberg原子云由双重光场打扮。这允许利用长寿的基础状态与自旋回声脉冲序列结合使用，以重新聚焦于ACHIRAL相互作用。确定了敷料激光器的最佳参数。将rydberg原子中的圆极化偶极转变与原子质量运动结合，系统变成手性。使用宏观量子电动力学方法估算了由手性镜诱导的歧视性手性能量变化。
A quantum sensing protocol is proposed for demonstrating the motion-induced chirality of circularly polarised Rydberg atoms. To this end, a cloud of Rydberg atoms is dressed by a bichromatic light field. This allows to exploit the long-lived ground states for implementing a Ramsey interferometer in conjunction with a spin echo pulse sequence for refocussing achiral interactions. Optimal parameters for the dressing lasers are identified. Combining a circularly polarised dipole transition in the Rydberg atom with atomic centre-of-mass motion, the system becomes chiral. The resulting discriminatory chiral energy shifts induced by a chiral mirror are estimated using a macroscopic quantum electrodynamics approach.
