Searching for symmetric mass generation with staggered fermions in four dimensions
Nouman Butt, Simon Catterall, Gwen Hartshaw +1
We conduct numerical simulations to map out the phase diagram and critical behavior of a lattice Higgs model composed of two massless staggered fermion fields forming a doublet und…

Quantum Ising Model on Dimensional Antide Sitter Space using Tensor Networks
Abhishek Samlodia, Simon Catterall, Alexander F. Kemper +2
We study the quantum Ising model on (2+1)-dimensional anti-de Sitter space using Matrix Product States (MPS) and Matrix Product Operators (MPOs). We explore the bulk phase diagram…

Symmetric Mass Generation with four SU(2) doublet fermions
Nouman Butt, Simon Catterall, Anna Hasenfratz
We study a single exactly massless staggered fermion in the fundamental representation of an gauge group. We utilize an nHYP-smeared fermion action supplemented with additi…
