Abstract

We investigate the infrared behaviour of the gluon propagator in Lan-dau gauge on a lattice with twisted boundary conditions. Analytic calculationsusing Dyson-Schwinger equations, exact renormalization group and stochasticquantization show that the Landau gauge gluon propagator approaches zerofor small momentum. On the other hand lattice calculations seem to indicatea non-zero infrared limit. One possible explanation for this difference is theexistence of zero-momentum fluctuation modes which potentially give rise to amassive contribution to the gluon propagator. Our simulations show that withtwisted boundary conditions these zero-momentum modes are suppressed andthe gluon propagator is reduced in the infrared compared to a periodic latticeensemble.
