摘要
研究两能级原子与热库(热辐射场)相互作用。对于任意强度耦合的情况,给出求解原子约化密度矩阵的方法。针对实例,分析原子约化密度矩阵非对角元,通过计算得到消除消相干时外加驱动场所必须满足的特性方程。
Interaction of two-level atom with a thermal radiation field is studied. The atom's reducible density rectangular arrary is gived by the intensity-dependent coupling. Taking f(N)=a^+a for example, the non-opposite angle element of atom's reducible density rectangular array is obtained. We work out the restriction equation that must be satisfied by the external controllable driving field when the decoherence is to be eliminated.
