SU(2) gauge theory with quarks at non-zero mass
Jarno Rantaharju, Tobias Rindlisbacher, Kari Rummukainen +2
We study SU(2) gauge field theory with quarks. The theory is asymptotically non-free and, at vanishing quark mass, governed by a Gaussian fixed point at long distances. On…
Spectrum of SU(2) gauge theory at large number of flavors
Jarno Rantaharju, Tobias Rindlisbacher, Kari Rummukainen +2
We present a numerical study of the spectrum of an asymptotically non-free gauge theory with massive fermion flavors. For such large number of flavors, asymptotic…
Computing general observables in lattice models with complex actions
Olmo Francesconi, Markus Holzmann, Biagio Lucini +2
The study of QFTs at finite density is hindered by the presence of the so-called sign problem. The action definition of such systems is, in fact, complex-valued making standard imp…
Sp(4) gauge theories on the lattice: Quenched fundamental and antisymmetric fermions
Ed Bennett, Deog Ki Hong, Jong-Wan Lee +6
We perform lattice studies of meson mass spectra and decay constants of the gauge theory in the quenched approximation. We consider two species of (Dirac) fermions as matte…
AVX-512 extension to OpenQCD 1.6
Ed Bennett, Mark Dawson, Michele Mesiti +1
We publish an extension of openQCD-1.6 with AVX-512 vector instructions using Intel intrinsics. Recent Intel processors support extended instruction sets with operations on 512-bit…
Benchmark results in the 2D lattice Thirring model with a chemical potential
Venkitesh Ayyar, Shailesh Chandrasekharan, Jarno Rantaharju
We study the two dimensional lattice Thirring model in the presence of a fermion chemical po- tential. Our model is asymptotically free, contains massive fermions that mimic a bary…
