Phase transition of Kitaev spin liquid described by quantum geometric tensor
Meng-Meng Lu, Zheng-Chuan Wang
Weinvestigate the topological phase transition of Kitaev spin liquid in an external magnetic field by calculating the Berry curvature and the Fubini-Study metric. Employing Jordan-…
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…
The non-equilibrium temperature beyond local equilibrium assumption
Zheng-Chuan Wang
In this manuscript, we propose a non-equilibrium temperature by a temperature dependent Vlasov equation for the charge particles transport through a environmental reservoir. A new…
