Center vortices as sources of Abelian dominance in pure SU(2) Yang-Mills theory
L. E. Oxman
We argue that in the infrared regime of continuum Yang-Mills theory, the possibility of a mass gap in the charged sector is closely associated with the center vortex sector. The an…

Attractive Casimir effect in an infrared modified gluon bag model
L. E. Oxman, N. F. Svaiter, R. L. P. G. Amaral
In this work, we are motivated by previous attempts to derive the vacuum contribution to the bag energy in terms of familiar Casimir energy calculations for spherical geometries. A…

A gauge invariant and string independent fermion correlator in the Schwinger model
D. G. Barci, L. E. Oxman, S. P. Sorella
We introduce a gauge invariant and string independent two-point fermion correlator which is analyzed in the context of the Schwinger model (QED_2). We also derive an effective infr…
