Multigrid for Chiral Lattice Fermions: Domain Wall
Richard C. Brower, M. A. Clark, Dean Howarth +1
Critical slowing down for the Krylov Dirac solver presents a major obstacle to further advances in lattice field theory as it approaches the continuum solution. We propose a new mu…
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…
Linear Sigma EFT for Nearly Conformal Gauge Theories
T. Appelquist, R. C. Brower, G. T. Fleming +11
We construct a generalized linear sigma model as an effective field theory (EFT) to describe nearly conformal gauge theories at low energies. The work is motivated by recent lattic…
Nonperturbative investigations of SU(3) gauge theory with eight dynamical flavors
Lattice Strong Dynamics, Collaboration, : +14
We present our lattice studies of SU(3) gauge theory with = 8 degenerate fermions in the fundamental representation. Using nHYP-smeared staggered fermions we study finite-tem…
Lattice Field Theory on Riemann Manifolds: Numerical Tests for the 2-d Ising CFT on
Richard C. Brower, Michael Cheng, George T. Fleming +4
We present a method for defining a lattice realization of the quantum field theory on a simplicial complex in order to enable numerical computation on a general Riemann manif…
