Geometric Phase in Kitaev Quantum Spin Liquid
Zheng-Chuan Wang
Quantum spin liquid has massive many spin entanglement in the ground state, we can evaluate it by the entanglement entropy, but the latter can not be observed directly by experimen…

The Non-Adiabatic Sub-Geometric Phase and Its Application on Quantum Transition
Zheng-Chuan Wang
Based on the adiabatic geometric phase concerning with density matrix[1] , we extend it to the sub-geometric phase in the non-adiabatic case. It is found that whatever the real par…
