Graded Projected Entangled-Pair State Representations and An Algorithm for Translationally Invariant Strongly Correlated Electronic Systems on Infinite-Size Lattices in Two Spatial Dimensions
Qian-Qian Shi, Sheng-Hao Li, Jian-Hui Zhao +1
An algorithm to find a graded Projected Entangled-Pair State representation of the ground state wave functions is developed for translationally invariant strongly correlated electr…

Quantum phase transitions and bifurcations: reduced fidelity as a phase transition indicator for quantum lattice many-body systems
Jin-Hua Liu, Qian-Qian Shi, Jian-Hui Zhao +1
We establish an intriguing connection between quantum phase transitions and bifurcations in the reduced fidelity between two different reduced density matrices for quantum lattice…

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…
