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…
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…
Fast Partitioning of Pauli Strings into Commuting Families for Expectation Value Measurements of Dense Operators
Nouman Butt, Andrew Lytle, Ben Reggio +1
The cost of measuring quantum expectation values of an operator can be reduced by grouping the Pauli string ( tensor product) decomposition of the operator into maximally co…
Simulating the Femtouniverse on a Quantum Computer
Nouman Butt, Patrick Draper, Jiayu Shen
We compute the low-lying spectrum of 4D SU(2) Yang-Mills in a finite volume using quantum simulations. In contrast to small-volume lattice truncations of the Hilbert space, we empl…
Symmetric Mass Generation in Lattice Gauge Theory
Nouman Butt, Simon Catterall, Goksu Can Toga
We construct a four dimensional lattice gauge theory in which fermions acquire mass without breaking symmetries as a result of gauge interactions. Our model consists of reduced sta…
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.…
