Entanglement entropy for the one-dimensional flat-band ferromagnetic Tasaki model: spontaneous symmetry breaking with one type-B Goldstone mode
Huan-Qiang Zhou, Qian-Qian Shi, Ian P. McCulloch +1
The one-dimensional flat-band ferromagnetic Tasaki model exhibits spontaneous symmetry breaking from to with one type-B Goldstone mode, featuring that th…
Entanglement entropy for a type of scale-invariant states in two spatial dimensions and beyond: universal finite-size scaling
Huan-Qiang Zhou, Qian-Qian Shi, Ian P. McCulloch +1
A generic scheme is proposed to investigate the entanglement entropy for a type of scale-invariant states, valid for orthonormal basis states in the ground state subspace of quantu…
Fractals and spontaneous symmetry breaking with type-B Goldstone modes: a perspective from entanglement
Huan-Qiang Zhou, Qian-Qian Shi, John O. Fjærestad +1
The one-dimensional spin- ferromagnetic Heisenberg model, as a paradigmatic example for spontaneous symmetry breaking (SSB) with type-B Goldstone modes (GMs), is e…
Exact matrix product state representations for a type of scale-invariant states
Huan-Qiang Zhou, Qian-Qian Shi, Ian P. McCulloch
Exact matrix product state representations for a type of scale-invariant states are presented, which describe highly degenerate ground states arising from spontaneous symmetry brea…
Entanglement and logarithmic spirals in a quantum spin-1 many-body system with competing dimer and trimer interactions
Huan-Qiang Zhou, Qian-Qian Shi, Ian P. McCulloch +1
Spontaneous symmetry breaking (SSB) with type-B Goldstone modes is investigated in the macroscopically degenerate phase for a quantum spin-1 many-body system with competing dimer a…
