Geometric entanglement and quantum phase transitions in two-dimensional quantum lattice models
Qian-Qian Shi, Hong-Lei Wang, Sheng-Hao Li +3
Geometric entanglement(GE), as a measure of multipartite entanglement, has been investigated as a universal tool to detect phase transitions in quantum many-body lattice models. We…
Non-local correlations in the Haldane phase for an XXZ spin-1 chain: A perspective from infinite matrix product state representation
Yao Heng Su, Sam Young Cho, Bo Li +2
String correlations are investigated in an infinite-size XXZ spin-1 chain. By using the infinite matrix product state representation, we calculate a long-range string order. In the…
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…
Bifurcation in ground-state fidelity for a one-dimensional spin model with competing two-spin and three-spin interactions
Hong-Lei Wang, Yan-Wei Dai, Bing-Quan Hu +1
A one-dimensional quantum spin model with the competing two-spin and three-spin interactions is investigated in the context of a tensor network algorithm based on the infinite matr…
Ground-State Fidelity and Kosterlitz-Thouless Phase Transition for Spin 1/2 Heisenberg Chain with Next-to-the-Nearest-Neighbor Interaction
Hong-Lei Wang, Ai-Min Chen, Bo Li +1
The Kosterlitz-Thouless transition for the spin 1/2 Heisenberg chain with the next-to-the-nearest-neighbor interaction is investigated in the context of an infinite matrix product…
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…
