Goldstone modes and the golden spiral in the ferromagnetic spin-1 biquadratic model
Huan-Qiang Zhou, Qian-Qian Shi, Ian P. McCulloch +1
Ferromagnetic ground states have often been overlooked in comparison to seemingly more interesting antiferromagnetic ground states. However, both the physical and mathematical stru…

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…
