Matrix Product Operator Constructions for Gauge Theories in the Thermodynamic Limit

Nicholas Godfrey, Ian P. McCulloch

We present a general method for simulating lattice gauge theories in low dimensions using infinite matrix product states (iMPS). A central challenge in Hamiltonian formulations of…

Spontaneous symmetry breaking with type-B Goldstone modes in the SO( $2 s + 1$ ) 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( $2 s + 1$ ) 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…
