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…

Fast Partitioning of Pauli Strings into Commuting Families for Optimal Expectation Value Measurements of Dense Operators
Ben Reggio, Nouman Butt, Andrew Lytle +1
The Pauli strings appearing in the decomposition of an operator can be can be grouped into commuting families, reducing the number of quantum circuits needed to measure the expecta…

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…
