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…
