Bipartite Sachdev-Ye Models with Read-Saleur Symmetries
J. Classen-Howes, P. Fendley, A. Pandey +1
We introduce an SU(M)-symmetric disordered bipartite spin model with unusual characteristics. Although superficially similar to the Sachdev-Ye model, it has several markedly differ…
Minimal Hubbard models of maximal Hilbert space fragmentation
Yves H. Kwan, Patrick H. Wilhelm, Sounak Biswas +1
We show that Hubbard models with nearest-neighbor hopping and a nearest-neighbor hardcore constraint exhibit `maximal' Hilbert space fragmentation in many lattices of arbitrary dim…
Discrete scale invariant fixed point in a quasiperiodic classical dimer model
Sounak Biswas, S. A. Parameswaran
We study close-packed dimers on the quasiperiodic Ammann-Beenker (AB) graph, that was recently shown to have the unusual feature that hard-core dimer constraints are exactly reprod…
Statistical mechanics of dimers on quasiperiodic Ammann-Beenker tilings
Jerome Lloyd, Sounak Biswas, Steven H. Simon +2
We study classical dimers on two-dimensional quasiperiodic Ammann-Beenker (AB) tilings. Despite the lack of periodicity we prove that each infinite tiling admits 'perfect matchings…
