三原子系统中的成对偶极-偶极相互作用效应

Effect of pairwise Dipole - Dipole interaction among three atoms Systems

P Anantha Lakshmi, Ashoka Vudayagiri, Shaik Ahmed

摘要:

本文研究了三个二能级原子通过偶极-偶极相互作用的系统。这种相互作用表现为一个原子的激发态与其最近邻原子的基态之间的相互作用。稳态人口的密度矩阵元素,并与只有两个原子时的情况进行比较。可以注意到,第三个原子改变了三个原子的行为。两种配置进行了分析,其中一个是三个原子是在一条线上,没有原子之间的相互作用在端点和其他原子形成一个闭环与每个原子相互作用与它的邻居。

英文摘要:

We present analysis of a system of three two-level atoms interacting with each other through the dipole-dipole interaction. The interaction manifests between excited state of one of the atoms and the ground state of its nearest neighbour. Steady state populations of the density matrix elements are presented and are compared with a situation when only two atoms are present. It can be noticed that the third atom modifies the behaviour of the three atoms. Two configurations are analysed, one in which the three atoms are in a line, with no interaction between atoms at the end points and the other in which the atoms form a closed loop with each atom interacting with both its neighbours.
