We study the infrared limit of Landau gluon and ghost propagators on large lattices and investigate how the behavior according to the so-called massive solution is affected by temperature.

The colour fields, created by static sources belonging to different
SU(3) representations, from the 3 to the 27,
are computed in quenched SU(3) lattice QCD, in a $24^3\times
48$ lattice at $\beta=6.2$ and $a=0.07261(85)\,fm$.
We utilize the technique of generalized Wilson Loops to localize the
sources, correlated with plaquettes to measure the
respective colour fields. We investigate...

We review the status of lattice simulations for propagators in Coulomb gauge. In particular, we focus on renormalization issues for the static propagators and on the relation to the Gribov-Zwanziger and dual-superconductor confinement mechanisms. We also show how a vanishing static Coulomb gauge gluon propagator can agree with the lattice Landau gauge results; the IR effective gluon mass in...

We derive a new Hamiltonian renormalisation group flow equation for Yang-Mills theory in Coulomb gauge. The flow equations for the static gluon and ghost propagators are solved numerically under the assumption
of a bare ghost gluon vertex. The resulting propagators are compared with lattice data and results obtained from the Dyson-Schwinger equations following from a variational solution of...

We propose a new approach to the study of the interquark poten-
tial in LGTs. Instead of looking at the expectation value of
Polyakov loop correlators we study the modifications induced in the
chromoelectric flux due to the presence of the Polyakov loops.
This approach is particularly effective in the case of abelian LGTs where,
with a careful use of duality relations this study can be...
