Filtered Rayleigh-Ritz is all you need
Ryan Abbott, Daniel C. Hackett, George T. Fleming +2
Recent work has shown that the (block) Lanczos algorithm can be used to extract approximate energy spectra and matrix elements from (matrices of) correlation functions in quantum f…
Near-conformal dynamics in a chirally broken system
Thomas Appelquist, Richard C. Brower, Kimmy K. Cushman +11
Composite Higgs models must exhibit very different dynamics from quantum chromodynamics (QCD) regardless whether they describe the Higgs boson as a dilatonlike state or a pseudo-Na…
Radial Lattice Quantization of 3D Field Theory
Richard C. Brower, George T. Fleming, Andrew D. Gasbarro +4
The quantum extension of classical finite elements, referred to as quantum finite elements ({\bf QFE})~\cite{Brower:2018szu,Brower:2016vsl}, is applied to the radial quantization o…
Stealth dark matter confinement transition and gravitational waves
R. C. Brower, K. Cushman, G. T. Fleming +11
We use non-perturbative lattice calculations to investigate the finite-temperature confinement transition of stealth dark matter, focusing on the regime in which this early-univers…
Automated label flows for excited states of correlation functions in lattice gauge theory
Kimmy K. Cushman, George T. Fleming
Extracting excited states from lattice gauge theory correlation functions can be achieved through chi-squared minimization fits or algebraic approaches such as the variational meth…
Lattice Gauge Theory for Physics Beyond the Standard Model
Richard C. Brower, Anna Hasenfratz, Ethan T. Neil +7
This document is one of a series of whitepapers from the USQCD collaboration. Here, we discuss opportunities for lattice field theory research to make an impact on models of new ph…
