Non-invertible symmetries and boundary conditions for the transverse-field Ising model
Huan-Qiang Zhou, Qian-Qian Shi
Non-invertible Kramers-Wannier (KW) duality symmetries are constructed for the transverse-field Ising model (TFIM) at the self-dual point under various boundary conditions (BCs), a…
Spontaneous symmetry breaking with type-B Goldstone modes in the SO() ferromagnetic model: an entanglement perspective
Qian-Qian Shi, Huan-Qiang Zhou, Murray T. Batchelor +1
Spontaneous symmetry breaking with type-B Goldstone modes is investigated in the SO() ferromagnetic model. A set of orthonormal basis states in the ground state subspace are…
Emergent Goldstone flat bands and spontaneous symmetry breaking with type-B Goldstone modes
Huan-Qiang Zhou, Jesse J. Osborne, Qian-Qian Shi +1
For a quantum many-body spin system undergoing spontaneous symmetry breaking with type-B Goldstone modes, a high degree of degeneracy arises in the ground state manifold. Generical…
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…
