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…
