A simple way to detect the state transition caused by the nondiagonal abelian Berry phase
X. B. Wang, K. Matsumoto, H. Fan +2
In a nondegenerate syste, the abelian Berry's phase will never cause transitions among the Hamiltonian's eigenstate. However, in a degenerate syatem, it is well known that the stat…
