The effects of quantum measurement on an excited Λ-type atom in three-dimensional photonic crystal
量子测量对三维光子晶体中Λ型原子动力学性质的影响

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.
