Abstract

Berry phase in a single quantum dot with Rashba spin-orbit coupling is investigated theoretically. Berry phases as functions of magnetic field strength, dot size, spin-orbit coupling and photon-spin coupling constants are evaluated. It is shown that the Berry phase will alter dramatically from 0 to 2π as the magnetic field strength increases. The threshold of magnetic field depends on the dot size and the spin-orbit coupling constant.
