Wigner-Yanase skew information, quantum entanglement and spin nematic quantum phase transitions in biquadratic spin-1 and spin-2 XY chains with single-ion anisotropies
Yan-Wei Dai, Sheng-Hao Li, Sam Young Cho +1
Quantum phase transitions (QPTs) between uniaxial or biaxial spin nematic (SN) phases are investigated in biquadratic spin-1 and spin-2 XY infinite chains with the rhombic- and uni…
Instability of the Luttinger liquids towards an exotic quantum state of matter with highly degenerate ground states: an anisotropic extension of the ferromagnetic spin-1 biquadratic model
Qian-Qian Shi, Yan-Wei Dai, Sheng-Hao Li +1
An extensive investigation, both numerical and analytical, is performed for an anisotropic extension of the ferromagnetic spin-1 biquadratic model. The ground state phase diagram a…
Duality and ground-state phase diagram for the quantum XYZ model with arbitrary spin in one spatial dimension
Qian-Qian Shi, Sheng-Hao Li, Huan-Qiang Zhou
Five duality transformations are unveiled for the quantum XYZ model with arbitrary spin in one spatial dimension. The presence of these duality transformations drastically redu…
Groundstate fidelity phase diagram of the fully anisotropic two-leg spin-1/2 XXZ ladder
Sheng-Hao Li, Qian-Qian Shi, Murray T. Batchelor +1
The fully anisotropic two-leg spin-1/2 ladder model is studied in terms of an algorithm based on the tensor network representation of quantum many-body states as an adaptatio…
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…
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…
