Finite-state automata for exact matrix product operators of tight-binding Hamiltonians: fractals, quasicrystals, trees and hyperbolic lattices
Marta Brzezińska, Jeanne Colbois, Loïc Herviou
Inspired by the recent progress in the simulation of tight-binding Hamiltonians on large lattices using tensor networks, we introduce a systematic matrix product operator (MPO) con…

Probing magnetic correlations in space and time within predefined topological sectors of a macroscopic spin liquid
Rémy Dangoisse, Jeanne Colbois, Laurent Del Rey +2
The triangular Ising antiferromagnet, with its residual entropy density and critical correlations at absolute zero, is the archetype of a two-dimensional spin liquid. Its ground st…

Excitation caging in a vertex-frustrated quasiperiodic Einstein artificial spin ice
T. Wang, F. Museur, G. M. Macauley +5
Naturally occurring bulk quasicrystals are rare, and magnetic instances are rarer still, with chemical constraints typically permitting the synthesis of approximants rather than tr…
