Topological analysis of the complex SSH model using the quantum geometric tensor
Eve Cheng, Murray T. Batchelor, Danny Cocks
This paper presents two methods for topological analysis of the complex Hermitian Su-Schrieffer-Heeger (SSH) model using the quantum geometric tensor: Berry phase and topological d…
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…
