当原子松驰时间比洞松驰时间长比得上或时,原子记忆效果发生。我们证明由使用存储器效果,获得在一双 Stokes 和反之间的高周波的 Einstein-Podolsky-Rosen 纠纷是可能的 -- 司烧在一个四波浪的混合系统的域。物理起源由于参量地放大的地被跟踪到处理状态的动态空 splittings。这机制为边带纠纷提供一个其他、有效的方法。[从作者抽象]
Atomic memory effects occur when the atomic relaxation times are comparable to or much longer than the cavlty relaxation times. We show that by using the memory effects, it is possible to obtain high-frequency Einstein- Podolsky-tlosen entanglement between a pair of Stokes and anti-Stokes fields in a four-wave mixing system. The physical origin is traced to the dynamical Stark splittings of dressed states due to the parametrically amplified fields. This mechanism provides an alternative and efficient way for sideband entanglement.
