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…
Absence of a critical nematic phase in the vicinity of the ferromagnetic point for the one-dimensional spin-1 bilinear-biquadratic model
Yan-Wei Dai, Qian-Qian Shi, Huan-Qiang Zhou +1
The absence of a critical nematic phase in the vicinity of the ferromagnetic point for the one-dimensional spin-1 bilinear-biquadratic model is demonstrated by means…
Fractal dimension and the counting rule of the Goldstone modes
Qian-Qian Shi, Yan-Wei Dai, Huan-Qiang Zhou +1
It is argued that there are a set of orthonormal basis states, which appear as highly degenerate ground states arising from spontaneous symmetry breaking with a type-B Goldstone mo…
