Gluon screening mass at finite temperature from Landau gauge gluon propagator in lattice QCD
P. J. Silva, O. Oliveira, P. Bicudo +1
We address the interpretation of the Landau gauge gluon propagator at finite temperature as a massive type bosonic propagator. Using pure gauge SU(3) lattice simulations at a fixed…
Flux tube widening in compact U (1) lattice gauge theory computed at T < Tc with the multilevel method and GPUs
A. Amado, N. Cardoso, P. Bicudo
We utilize Polyakov loop correlations to study d=3+1 compact U (1) flux tubes and the static electron-positron potential in lattice gauge theory. With the plaquette field operator,…
Inside the SU(3) quark-antiquark QCD flux tube: screening versus quantum widening
N. Cardoso, M. Cardoso, P. Bicudo
In lattice QCD, colour confinement manifests in flux tubes. We compute in detail the quark-antiquark flux tube for pure gauge SU(3) dimension for quark-antiquark distances…
Landau gauge fixing on the lattice using GPU's
Nuno Cardoso, Paulo J. Silva, Orlando Oliveira +1
In this work, we consider the GPU implementation of the steepest descent method with Fourier acceleration for Laudau gauge fixing, using CUDA. The performance of the code in a Tesl…
