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…
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…
The ground-state phase diagram for an alternative anisotropic extension of quantum spin-1 ferromagnetic biquadratic model
Yan-Wei Dai, Qian-Qian Shi, Xi-Hao Chen +1
The ground-state phase diagram is mapped out for an alternative anisotropic extension of quantum spin-1 ferromagnetic biquadratic model, which accommodates twelve distinct phases:…
An alternative spontaneous symmetry breaking pattern for with no gapless Goldstone mode
Huan-Qiang Zhou, Qian-Qian Shi, Yan-Wei Dai
An emergent gapless Goldstone mode originates from continuous spontaneous symmetry breaking, which has become a doctrine since the pioneering work by Goldstone [J. Goldstone, Nuovo…
