摘要/Abstract

摘要：基于格林函数预解算子方法，研究了纳米银球附近V型三能级原子的自发辐射动力学特性.结果表明，原子的自发辐射动力学强烈依赖于原子的跃迁频率和所处位置.原子动力学演化谱呈现出双主峰的特征，距离较近时，高频峰宽度远小于低频峰宽度；自发辐射动力学振荡频率由演化谱双峰频率差决定，而振荡衰减快慢主要由演化谱峰宽决定；距离越近，相干振荡越强；2个跃迁频率越接近自发辐射增强谱峰值频率，演化谱峰高越低，尤其是低频峰，相干振荡越弱.

Abstract: Based on the method of Green's function presolvation operator,the spontaneous radiation dynamics of V-type three-level atoms near silver nanospheres are studied.The effects of atomic transition frequency and atomic distance on the surface of the nanosphere on the spontaneous radiation dynamics are investigated systematically.The results show that when the transition frequency of the atom is far away from the resonant frequency of the isoplasmon,the evolution spectrum of the atom is half high and narrow,the dynamic oscillation is enhanced,and the decay rate is slow with time.When the two transition frequencies are close to the formant frequency,the kinetic oscillation of the atom is weakened,and the attenuation rate is faster with time.The distance between the atom and the surface of the nanosphere plays an important role in the coherent oscillation.The closer the distance,the stronger the coherent oscillation;and the farther the distance,the weaker the coherent oscillation.
