Quantum phase transitions in a two-dimensional quantum XYX model: Ground-state fidelity and entanglement
Bo Li, Sheng-Hao Li, Huan-Qiang Zhou
A systematic analysis is performed for quantum phase transitions in a two-dimensional anisotropic spin 1/2 anti-ferromagnetic XYX model in an external magnetic field. With the help…

Singularities in ground state fidelity and quantum phase transitions for the Kitaev model
Jian-Hui Zhao, Huan-Qiang Zhou
The ground state fidelity per lattice site is shown to be able to detect quantum phase transitions for the Kitaev model on the honeycomb lattice, a prototypical example of quantum…

Deriving local order parameters from tensor network representations
Huan-Qiang Zhou
A large class of quantum phase transitions for quantum lattice systems are characterized by local order parameters. It is shown that local order parameters may be systematically co…
