    "abstract": "There is a good deal of current interest in the condensate g^2A_\\mu^aA_a^\\mu\u003e\nwhich has recently be shown to be the Landau gauge version of a more general\ngauge-invariant expression. In the present work we consider quark propagation\nin the presence of such a condensate which we assume to be present in the\nvacuum. We describe the vacuum as a random medium of gluon fields. We discuss\nquark propagation in that medium and show that the quark propagator has no\non-mass-shell pole indicating that a quark cannot propagate over extended\ndistances. That is, the quark is a nonpropagating mode in the gluon condensate.",
