Adiabatic Geometric Phase for a General Quantum States
Biao Wu, Jie Liu, Qian Niu
A geometric phase is found for a general quantum state that undergoes adiabatic evolution. For the case of eigenstates, it reduces to the original Berry's phase. Such a phase is ap…

Geometric Phases for Mixed States during Cyclic Evolutions
Li-Bin Fu, Jing-Ling Chen
The geometric phases of cyclic evolutions for mixed states are discussed in the framework of unitary evolution. A canonical one-form is defined whose line integral gives the geomet…
