Exponential Error Reduction for Glueball Calculations Using a Two-Level Algorithm in Pure Gauge Theory
Lorenzo Barca, Francesco Knechtli, Sofie Martins +3
This study explores the application of a two-level algorithm to enhance the signal-to-noise ratio of glueball calculations in four-dimensional pure gauge theory. O…
The quark-mass dependence of the potential energy between static colour sources in the QCD vacuum with light and strange quarks
John Bulava, Francesco Knechtli, Vanessa Koch +2
The low-lying energy spectrum of the static-colour-source-anti-source system in a vacuum containing light and strange quarks is computed using lattice QCD for a range of different…
Simulation of dynamical fermions with smeared links
A. Hasenfratz, F. Knechtli
Smearing the gauge links of dynamical configurations removes small scale unphysical vacuum fluctuations und thus improves the chiral properties of lattice fermions. We present a ne…
The phase diagram of QCD with two and four flavors: results with HYP fermions
A. Hasenfratz, F. Knechtli
We study the finite temperature phase transition of four and two flavor staggered fermions with hypercubic smeared link actions. These preliminary studies suggest that the improved…
The Static Potential with Hypercubic Blocking
A. Hasenfratz, R. Hoffmann, F. Knechtli
We measure the static potential from Wilson loops constructed using hypercubic blocked (HYP) links. The HYP potential agrees with the potential measured using thin links for distan…
Simulating dynamical fermions with smeared links
A. Hasenfratz, F. Knechtli
Smearing the gauge links of dynamical configurations removes small scale unphysical vacuum fluctuations and thus improves the chiral properties of lattice fermions. Recently we pro…
