光学微腔是目前凝聚态物理的研究热点，它能够改变自发发射的特性(谱线宽度、发光强度等) 。 - We use full quantum theory to investigate the decay distribution of atoms in one - dimensional photonic crystal and the quantum interference property of a v - type three - level atom placed between two parallel plates
采用全量子理论，本文研究了一维光子晶体中原子自发发射的寿命分布和置于两平板介质之间的v型三能级原子的量子干涉性质。 - Through the calculation of the electromagnetic green ' s function , we investigate the spontaneous emission behavior from atoms in one - dimensional photonic crystal . we found that the pc effect may lead to the coexistence of both accelerated and inhibited decay processes
通过计算一维光子晶体中电磁场的green函数，我们考察了一维光子晶体中原子自发发射的寿命分布，发现光子晶体效应能使原子自发发射速率加快或减慢。 - Abstract : we have studied the spontaneous emission from a three - level atom with an external - driving field in a photonic crystal . as a result of quantum interference and photon localization , the population in the two upper levels displays quasi - oscillatory oroscillatory behavior . this depends on the initial atomic state and the relative positions of the two upper levels from the forbidden gap . the intensity and the phase of the external field can affect spontaneous emission from the atom . the properties are different from a three - level atom either in vacuum or in aphotonic crystal without an external driving field
文摘:讨论了在双光子驱动场作用下，三能级原子在光子晶体中的自发发射问题.由于量子干涉和光的局域化作用，两个上能级中的占据数将具有周期振荡或准周期振荡的性质，这不仅依赖于两个上能级与禁带的相对位置，同时也依赖于原子的初始状态，而且还与驱动场的强度、驱动场的入射位相有关.这些性质既与真空中带有驱动场的原子的自发发射性质不同，也有别于无驱动场作用下光子晶体中三能级原子的自发发射性质
