Entanglement entropy for scale-invariant states: universal finite-size scaling
Huan-Qiang Zhou, Qian-Qian Shi, Ian P. McCulloch +1
A universal finite system-size scaling analysis of the entanglement entropy is presented for highly degenerate ground states arising from spontaneous symmetry breaking with type-B…

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…
