Geometric entanglement from matrix product state representations
Bing-Quan Hu, Xi-Jing Liu, Jin-Hua Liu +1
An efficient scheme to compute the geometric entanglement per lattice site for quantum many-body systems on a periodic finite-size chain is proposed in the context of a tensor netw…
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…
Ground-state fidelity and tensor network states for quantum spin tubes
Ai-Min Chen, Qian-Qian Shi, Jin-Hua Liu +1
An efficient algorithm is developed for quantum spin tubes in the context of the tensor network representations. It allows to efficiently compute the ground-state fidelity per latt…
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…
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…
