二维二能级系统最一般哈密顿量的$Sp(4,R)$代数方法

$Sp(4,R)$ algebraic approach of the most general Hamiltonian of a two-level system in two-dimensional geometry

E. Choreño, D. Ojeda-Guillén

摘要:

本文在$SU(1,1)$和$SU(2)$群论的基础上,引入了$sp(4,R)$代数的玻色生成元,并研究了它们的一些性质.利用$Sp(4,R)$群理论,我们精确地求解了二维几何中二能级系统最一般哈密顿量的相互作用部分。作为这种哈密顿量的特殊情况下,我们再现的狄拉克振荡器和Jaynes-Cummings模型的一个和两个振荡模式的早期问题的解决方案。

英文摘要:

In this paper we introduce the bosonic generators of the $sp(4,R)$ algebra and study some of their properties, based on the $SU(1,1)$ and $SU(2)$ group theory. With the developed theory of the $Sp(4,R)$ group, we solve the interaction part of the most general Hamiltonian of a two-level system in two-dimensional geometry in an exact way. As particular cases of this Hamiltonian, we reproduce the solution of earlier problems as the Dirac oscillator and the Jaynes-Cummings model with one and two modes of oscillation.
