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…
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…
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…
Moving from continuous to discrete symmetry in the 2D XY model
Nouman Butt, Xiao-Yong Jin, James C Osborn +1
We study the effects of discretization on the U(1) symmetric XY model in two dimensions using the Higher Order Tensor Renormalization Group (HOTRG) approach. Regarding the sy…
