李量子系统时间演化算符的几何方法

A geometric approach to time evolution operators of Lie quantum systems

José F. Cariñena, Javier de Lucas, Arturo Ramos

摘要:

从几何的观点研究了量子力学中的李系统。特别是,我们开发的方法来获得时间依赖薛定谔方程的李型的时间演化算子,我们展示了这些方法如何解释某些特设的方法在以前的论文中使用,以获得精确的解决方案。最后,求解了几个含时二次哈密顿量的例子。

英文摘要:

Lie systems in Quantum Mechanics are studied from a geometric point of view. In particular, we develop methods to obtain time evolution operators of time-dependent Schrodinger equations of Lie type and we show how these methods explain certain ad hoc methods used in previous papers in order to obtain exact solutions. Finally, several instances of time-dependent quadratic Hamiltonian are solved.
