腔体QED“通过数字”

Cavity QED "By The Numbers"

J. McKeever, J. R. Buck, A. D. Boozer, H. J. Kimble

摘要:

通过监测弱探测光束的传输,实时确定被捕获在光学腔模式内的原子数量。原子数的连续观测是在腔量子电动力学的强耦合机制中完成的,并与原子径向运动的冷却方案相一致。探针传输表现出突然的步骤,从一个平台到下一个响应于腔内原子数的时间演化,从N >= 3到N = 2到1到0,与一些捕获事件持续超过1秒。

英文摘要:

The number of atoms trapped within the mode of an optical cavity is determined in real time by monitoring the transmission of a weak probe beam. Continuous observation of atom number is accomplished in the strong coupling regime of cavity quantum electrodynamics and functions in concert with a cooling scheme for radial atomic motion. The probe transmission exhibits sudden steps from one plateau to the next in response to the time evolution of the intracavity atom number, from N >= 3 to N = 2 to 1 to 0, with some trapping events lasting over 1 second.
