Universal construction of order parameters for translation-invariant quantum lattice systems with symmetry-breaking order
Jin-Hua Liu, Qian-Qian Shi, Hong-Lei Wang +2
For any translation-invariant quantum lattice system with a symmetry group G, we propose a practical and universal construction of order parameters which identify quantum phase tra…

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…
