Webwhich can be parameter dependent. The Berry phase is unchanged up to integer multiple of 2 by such a phase factor, provided the eigenwave function is kept to be single valued over the loop. This property makes the Berry phase physical, and the early experimental studies were focused on measuring it directly through interfer-ence phenomena ... WebOct 30, 2009 · There is not a Plane/Arc intersection there, but there is a Plane/Sphere intersection method that might be promising. Essentially, you could use the Plane/Sphere intersection with the sphere being generated from the center point & radius of the arc, with the result of that intersection being a circle. Then you would do use the IntersectCurve ...

In classical and quantum mechanics, geometric phase is a phase difference acquired over the course of a cycle, when a system is subjected to cyclic adiabatic processes, which results from the geometrical properties of the parameter space of the Hamiltonian. The phenomenon was independently discovered by S. Pancharatnam (1956), in classical optics and by H. C. Longuet-Higgins (1958) in molecular physics; it was generalized by Sir Michael Berry in (1984). It is also k…
