【摘要】 光场与窄能带晶体的强耦合体系被发现存在一种新型的元激发——能级激元。我们分析了该元激发的能谱及一些性质。并提出通过控制光场的状态来实现能级激元的态制备。更多还原

【Abstract】 The strong coupled systems of the optical field and the narrow band crystals are found to exist a new kind of elementary excitation energy level excitation.The energy spectrum and some other properties of this exciation are analysed and some kinds of states of the excitation are prepared by controling the states of the incident optical field.更多还原
