Quantum entanglement entropy and Tomonaga-Luttinger liquid to liquid transition in biquadratic spin-1 XY chain with rhombic single-ion anisotropy
Yan-Wei Dai, Yao Heng Su, Sam Young Cho +1
Quantum phase transitions (QPTs) are investigated in biquadratic spin- XY chain with rhombic single-ion anisotropy by using the ground state energy (GE), the bipartite entanglem…
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…
The ground-state phase diagram for an alternative anisotropic extension of quantum spin-1 ferromagnetic biquadratic model
Yan-Wei Dai, Qian-Qian Shi, Xi-Hao Chen +1
The ground-state phase diagram is mapped out for an alternative anisotropic extension of quantum spin-1 ferromagnetic biquadratic model, which accommodates twelve distinct phases:…
An alternative spontaneous symmetry breaking pattern for with no gapless Goldstone mode
Huan-Qiang Zhou, Qian-Qian Shi, Yan-Wei Dai
An emergent gapless Goldstone mode originates from continuous spontaneous symmetry breaking, which has become a doctrine since the pioneering work by Goldstone [J. Goldstone, Nuovo…
Extracting the number of type-B Goldstone modes and the dynamical critical exponent for a type of scale-invariant states
Huan-Qiang Zhou, Yan-Wei Dai, Qian-Qian Shi +2
A generic scheme is proposed to perform a finite-entanglement scaling analysis for scale-invariant states, which appear to be highly degenerate ground states arising from spontaneo…
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…
