Bifurcation in ground-state fidelity and universal order parameter for two-dimensional quantum transverse Ising model
Sheng-Hao Li, Hong-Lei Wang, Qian-Qian Shi +1
We establish an intriguing connection between quantum phase transitions and bifurcations in the ground-state fidelity per lattice site, and construct the universal order parameter…
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…
