Effects of quantum geometric phase of a particle in an oscillating hard-wall spherical trap

Abstract

We obtain the geometric phase for states of a particle in a spherical infinite potential well with a moving wall in two different cases; First, when the radius of the well increases (or decreases) monotonically. Second, when the radius changes oscillatory. In the latter case, we have solved the Schrodinger equation and found its solutions approximately. {We obtain the transition rate for the possible real situation in an acousto-optic case which can reveal the effect of the geometric phase. We show that the absorption or radiation peaks will appear if the energy gap between the incident photon and the modified energy difference of two levels by the geometric phase, is equal to the integer multiple of oscillation frequency.
