三维各向同性谐振子的代数解法 总被引:1,自引:0,他引:1
用带角动量的玻色算子统一构成三维各向同性谐振子的能量本征函数,并讨论了它们和直接求解微分方程得到的本征解之间的关系.这种方法快捷优美,而且有统一的表达式和简单的李代数关系。 相似文献

基于表述经典及量子系统可积性的动力对称性群,对量子可积系统规则运动的经典对应问题运用归纳法进行了研究.具体给出了经典近似描述的适用条件,并进行了简明讨论.Based on the dynamical symmetry group characterizing the integrability of classical as well as quantum mechanics, quantum dynamics with proper initial conditions was genuinely formulated, and analytical solutions in the form of soliton-like state evolving around a certain invariant torus were obtained. It has been shown that, in case the intrinsic size of the evolving quantum state is significantly smaller than the extent of its evolving orbit, the motion can be satisfactorily treated with... 相似文献
