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…
