The Chern-Simons term in a dual Josephson junction
L. S. Grigorio, M. S. Guimaraes, R. Rougemont +2
A dual Josephson junction corresponding to a (2+1)-dimensional non-superconducting layer sandwiched between two (3+1)-dimensional dual superconducting regions constitutes a model o…
The BF theory as an electric Julia-Toulouse condensate
L. S. Grigorio, M. S. Guimaraes, R. Rougemont +2
The Julia-Toulouse mechanism is used to show that the topological Abelian BF term may be induced by the condensation of electric charges. As an application we discuss the subtle qu…
Effective confinement theory from Abelian variables in SU(3) gauge theory
L. S. Grigorio, M. S. Guimaraes, R. Rougemont +1
In this Letter we use the Julia-Toulouse approach for condensation of defects in order to obtain an effective confinement theory for external chromoelectric probe charges in SU(3)…
U(1) effective confinement theory from SU(2) restricted gauge theory via the Julia-Toulouse Approach
L. S. Grigorio, M. S. Guimaraes, W. Oliveira +2
We derive an U(1) effective theory of color confinement by applying the so-called Julia-Toulouse Approach for defects condensation to the SU(2) restricted gauge theory defined by m…
Lorentz-violating Chern-Simons action under high temperature in massless QED
F. A. Brito, L. S. Grigorio, M. S. Guimaraes +2
Lorentz and CPT violating QED with massless fermions at finite temperature is studied. We show that there is no ambiguity in the induced coefficient of the Chern-Simons-like term t…
Induced Chern-Simons-like action in Lorentz-violating massless QED
F. A. Brito, L. S. Grigorio, M. S. Guimaraes +2
In the present work, we study different aspects of Lorentz and CPT symmetry violation in extended massless QED. By following the observation that the 2+1 dimensional Maxwell-Chern-…
