| Abstract: | By generalizing the zheory of high-order approximation based on the biorthonormal State method,the adiabotic evolution and non-adiabatic Corrections are studied for the degenerate guantum system of the non-hermition Hamiltonian with Slowly-Changing Parameters.It is Shown that the Complexized Berry's phase factor will appear in the evolution of state of the system.Its gauge properties are also studied. |
