电介质自发衰减的微观理论

Microscopic Theory of Spontaneous Decay in a Dielectric

Hao Fu, P. R. Berman

摘要:

本文计算了无序介质中杂质源原子自发放电率的局域场修正,修正系数按介质密度的二阶近似计算。结果被发现与“虚拟”和“真实”的腔模型的这种衰变过程的预测不同。然而,如果包括两个在同一位置的介质原子的贡献,虚拟腔的结果再现。

英文摘要:

The local field correction to the spontanous dacay rate of an impurity source atom imbedded in a disordered dielectric is calculated to second order in the dielectric density. The result is found to differ from predictions associated with both "virtual" and "real" cavity models of this decay process. However, if the contributions from two dielectric atoms at the same position are included, the virtual cavity result is reproduced.
