中文摘要：

讨论了量子测量对各向异性光子晶体中Λ型激发态原子衰减的影响,主要包括衰减的抑制和加速效应.研究发现,这样的量子测量效应不仅与原子共振频率相对于光子晶体带边的位置有关,还与量子测量本身的频率大小相关.由于各向异性光子晶体的影响,较小频率的量子测量也能得到抑制衰减的效应.

英文摘要：

We have studied the effects of quantum measurements on the decay of an excited A-type atom embedded in anisotropic photonic crystal. It is found that the decay of the atom can be suppressed or accelerated by the quantum measurements. This depends on the relative positions of the upper levels of the atom from the band edge and the frequency of the quantum measurements. Due to the effects of the anisotropic photonic crystal, the decay suppression effect can be obtained in relatively low frequencies of the quantum measurement.
