量子微腔中腔场衰变对运动原子自发辐射的影响

The Effect of Spontaneous Emission of Motive Atoms in Damping Fieldof A Quantum Micro -Cavity

通过分析环形微腔中单模量子电磁场与低速运动二能级原于相互作用过程中光子与原子质心的动量交换效应,本文详细地研究了原子质心的运动多谱勒效应及光子反冲对原了能级自发辐射寿命的影响。本文理论证明了这效应起因于腔壁引起腔模的衰变,在一定条件下,原子质心运动将增强或压低原子的自发辐射。

By analysing the effect of momentum exchange between photon and atom in the interaction process of single mode field and two -level motive atoms with low speed in a ring microcavity, the life time of atom spontaneous emission is comprehensively investigated. It shows that this effect results from the damping of the cavity mode. On certain conditions, the spontaneous emission of atoms will be increased or decreased by the motion of atoms.
