Abstract

In this paper we show that the Berry phase can always be cancelled by a unitary transformation if the space of external parameters is appropriately restricted, but it simply reappears as part of the dynamical phase. Moreover the overall extra geometrical phase measured in experiments is unambiguous and retains its geometrical character.
