摘要
研究了准Λ型四能级原子与多模光场相互作用的量子系统.在量子干涉机理下,原子的相对介电常数和相对磁导率受相干光场诱导发生显著变化,在合适的参数区间内,它们同时出现负值,即产生了左手效应.
The quantum mechanics system with interaction between quasi-A type four-level atoms and multi-mode light fields is discussed. Under the mechanism of quantum interference, the relative dielectric permittivity and the relative magnetic permeability will change remarkably. In certain range of parameters, both of them will be negative. At this time, the lefthandedness effect happens.
