耦合异向介质的量子描述与受激发射辐射

The quantum description and stimulated emission radiation of coupled metamaterials

Shuming Wang, Hui Liu, Tao Li, Shining Zhu, Xiang Zhang

摘要:

近年来,人们对等离子体超材料的量子特性的研究越来越感兴趣。利用哈密顿量和二次量子化相结合的方法,研究了耦合异向介质的基本激发,给出了耦合异向介质的量子描述。利用相互作用哈密顿量进一步研究了耦合超材料的激发与量子点材料中激子的相互作用。在这样的阻尼系统中,一组朗之万方程被用来处理系统的量子运动。并发现了受激发射,可用于形成纳米激光器。耦合超材料及其相互作用系统的量子描述可以作为研究耦合超材料中量子效应的基本方法。

英文摘要:

In recent years, there has been increasing interest in studying the quantum characteristics in plasmonic metamaterials. By using the Hamiltonian combined with second quantization, we have investigated the basic excitation of the coupled metamaterials and presented a quantum description of them. The interaction between the excitation of the coupled metamaterial and the exciton in the quantum dot material has been further considered with the aid of the interaction Hamiltonian. In such a damping system, a set of Langevin equations has been used to deal with the quantum motion of the system. And the stimulated emission has been found, which can be used to form a nano-laser. The quantum description of coupled metamaterial and the interaction system could work as the fundamental method in paving the way for studies on quantum effects in coupled metamaterials.
