非模拓扑相和相奇点

The nonmodular topological phase and phase singularities

Rajendra Bhandari

摘要:

推广非循环几何相位的较早定义(R.Bhandari,Phys.Lett.A,157,221(1991)),参照涉及具有N个内部状态的粒子的一般时间相关双缝干涉实验来定义非模拓扑相位,其中两个光束的内部状态经历幺正演化。一个简单的证明较短的测地线规则封闭的开放路径和几个有用的新的见解的行为的动力学和几何组件的相移。一个有效的哈密顿解释的可观察到的相移。

英文摘要:

Generalizing an earlier definition of the noncyclic geometric phase (R.Bhandari, Phys.Lett.A, 157, 221 (1991)), a nonmodular topological phase is defined with reference to a generic time-dependent two-slit interference experiment involving particles with N internal states in which the internal state of both the beams undergoes unitary evolution. A simple proof of the shorter geodesic rule for closure of the open path is presented and several useful new insights into the behaviour of the dynamical and geometrical components of the phase shift presented. An effective hamiltonian interpretation of the observable phase shifts is also presented.
