Abstract
In the Coulomb gauge, the solution to the Maxwell equations for slowly time-varying homogeneous nondispersive conducting linear media without charge source is obtained. We show that the electromagnetic field acquires the extra geometrical Hannay angle associated to the time-dependent generalized harmonic oscillator. The quantization scheme for the electromagnetic field provides a connection between the classical Hannay angle and the quantum adiabatic Berry phase shifts. We confirm that the interference pattern in the optical system is more or less altered by the existence of the geometric phase.
