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() 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…
Phase diagram of the quantum Ising model with long-range interactions on an infinite-cylinder triangular lattice
S. N. Saadatmand, S. D. Bartlett, I. P. McCulloch
Obtaining quantitative ground-state behavior for geometrically-frustrated quantum magnets with long-range interactions is challenging for numerical methods. Here, we demonstrate th…
