Inconsistencies of the Adiabatic Theorem and the Berry Phase
... Recently, Marzlin and Sanders (MS) have pointed out an inconsistency in the quantum adiabatic theorem [11]. In this paper we resolve their inconsistency. However, our resolution leads to another inconsistency, namely, under strict adiabatic approximation cyclic as well as non-cyclic Berry phase almo ...
