Exotic Phases of a Higgs-Yukawa Model with Reduced Staggered Fermions
Simon Catterall, Nouman Butt, David Schaich
We investigate the phase structure of a four dimensional SO(4) invariant lattice Higgs-Yukawa model comprising four reduced staggered fermions interacting with a real scalar field.…

Tensor network formulation of the massless Schwinger model
Nouman Butt, Simon Catterall, Yannick Meurice +1
We construct a tensor network representation of the partition function for the massless Schwinger model on a two dimensional lattice using staggered fermions. The tensor network re…

Four fermion condensates in Yang-Mills-Higgs theory on a lattice
Nouman Butt, Simon Catterall
We study a model of four reduced staggered fields transforming in the bifundamental representation of a symmetry group where just one of the SU(2) factors is ga…
