An efficient computation of geometric entanglement for two-dimensional quantum lattice systems
Hong-Lei Wang, Qian-Qian Shi, Sheng-Hao Li +1
The geometric entanglement per lattice site, as a holistic measure of the multipartite entanglement, serves as a universal marker to detect quantum phase transitions in quantum man…
Ground-state fidelity and quantum criticality in a two-leg ladder with cyclic four-spin exchange
Sheng-Hao Li, Qian-Qian Shi, Jin-Hua Liu +1
We investigate a two-leg Heisenberg spin ladder with cyclic four-spin exchange by exploiting a newly-developed tensor network algorithm. The algorithm allows to efficiently compute…
Tensor network states for quantum spin ladders
Sheng-Hao Li, Yao-Heng Su, Yan-Wei Dai +1
We have developed an efficient tensor network algorithm for spin ladders, which generates ground-state wave functions for infinite-size quantum spin ladders. The algorithm is able…
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 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…
