Abstract
The authors calculate Berry's phase and the Hannay angle for some physically interesting coherent states with the parameters characterising the coherent states taken to be slowly varying. Interestingly, they find that the harmonic oscillator coherent states provide an example for which, although the Hannay angle is zero, Berry's phase is non-zero.Keywords
