Quantum fidelity for degenerate groundstates in quantum phase transitions
Yao Heng Su, Bing-Quan Hu, Sheng-Hao Li +1
Spontaneous symmetry breaking mechanism in quantum phase transitions manifests the existence of degenerate groundstates in broken symmetry phases. To detect such degenerate grounds…
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…
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…
