The lattice infrared Landau gauge gluon propagator: the infinite volume limit

- O. Oliveira, P. J. Silva
- Physics, Mathematics
- 15 October 2009

We report on the infrared behaviour of the lattice gluon propagator. The bounds on D(0) and their behaviour with the lattice volume are investigated, together with the full propagator. Moreover, a… Expand

The lattice infrared Landau gauge gluon propagator: from finite volume to the infinite volume

- O. Oliveira, P. J. Silva
- Physics
- 9 November 2009

The Landau gauge lattice gluon propagator is discussed for different sets of lattices. Particular attention is given to its infrared properties. Our results show that the lattice propagator can be… Expand

The lattice gluon propagator in renormalizable $\xi$ gauges

- P. Bicudo, D. Binosi, N. Cardoso, O. Oliveira, P. J. Silva
- Physics
- 21 May 2015

We study the SU(3) gluon propagator in renormalizable $R_\xi$ gauges implemented on a symmetric lattice with a total volume of (3.25 fm)$^4$ for values of the guage fixing parameter up to $\xi=0.5$.… Expand

Gluon screening mass at finite temperature from the Landau gauge gluon propagator in lattice QCD

- P. J. Silva, O. Oliveira, P. Bicudo, N. Cardoso
- Physics
- 21 October 2013

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 lattice volume… Expand

Improving dynamical lattice QCD simulations through integrator tuning using Poisson brackets and a force-gradient integrator

- M. Clark, B. Jo'o, A. Kennedy, P. J. Silva
- Physics
- 8 August 2011

We show how the integrators used for the molecular dynamics step of the Hybrid Monte Carlo algorithm can be further improved. These integrators not only approximately conserve some Hamiltonian H but… Expand

What does low energy physics tell us about the zero momentum gluon propagator

- P. Costa, O. Oliveira, P. J. Silva
- Physics
- 25 November 2010

Force-gradient integrators

- A. Kennedy, M. Clark, P. J. Silva
- Physics
- 15 October 2009

We present initial results of the use of Force Gradient integ rators for lattice field theories. These promise to give significant performance improvements, espe cially for light fermions and large… Expand

Just how different are SU(2) and SU(3) Landau-gauge propagators in the IR regime?

- A. Cucchieri, T. Mendes, O. Oliveira, P. J. Silva
- Physics
- 23 May 2007

The infrared behavior of gluon and ghost propagators in Yang-Mills theories is of central importance for understanding quark and gluon confinement in QCD. While simulations of pure SU(3) gauge theory… Expand

Shadow Hamiltonians, Poisson brackets, and gauge theories

- A. Kennedy, P. J. Silva, M. Clark
- Physics
- 24 October 2012

Numerical lattice gauge theory computations to generate gauge field configurations including the effects of dynamical fermions are usually carried out using algorithms that require the molecular… Expand
