Berry geometric phase in oscillatory processes
Lomonosov Moscow State University, Department of Physics, Leninskie Gory 1 build. 2, Moscow, 119991, Russian Federation
Useful physical models that reveal the basic physical properties of the Berry phase are presented. They include Foucault's pendulum, rotation of the plane of polarization of light by three mirrors, and so on. Particular attention is devoted to the phase that arises when the polarization of light is transformed by an anisotropic medium. This is used to introduce modern terminology and then to examine more general situations. Several terminological and methodological questions are examined.
