Thick oriented and nonoriented center-vortex configurations with fractional topological charge lumps
David R. Junior, L. E. Oxman, Gustavo M. Simões
Mixed oriented and nonoriented center vortices are known to generate nontrivial topological charge. However, most previous analyses have been restricted to Abelian-projected thin c…
Vacuum fluctuations in the presence of nonlinear boundary conditions
C. D. Fosco, L. E. Oxman
We consider a system consisting of a quantum, massless, real scalar field, in the presence of nonlinear mirrors: infinite parallel planes, upon which the field satisfies nonlinear…
Coloured loops in 4D and their effective field representation
L. E. Oxman, G. C. Santos Rosa, B. F. I. Teixeira
Gaining insight about ensembles of magnetic configurations, that could originate the confining string tension between quarks, constitutes a major concern in current lattice investi…
On the induced gauge invariant mass
C. D. Fosco, L. E. Oxman, S. P. Sorella
We derive a general expression for the gauge invariant mass (m_G) for an Abelian gauge field, as induced by vacuum polarization, in 1+1 dimensions. From its relation to the chiral…
