Exciton BCS or BEC state in a semiconductor bilayer system?
E. H. Martins Ferreira, Tathiana Moreira, M. C. Nemes
We calculate the off-diagonal long range order (ODLRO) terms of the exciton--exciton correlation function of a semiconductor bilayer system with Coulomb interaction and a transvers…
Gauge invariance and the CPT and Lorentz violating induced Chern-Simons-like term in extended QED
A. P. Baeta Scarpelli, Marcos Sampaio, M. C. Nemes +1
The radiative induction of the CPT and Lorentz violating Chern-Simons (CS) term is reassessed. The massless and massive models are studied. Special attention is given to the preser…
Implicit regularization beyond one loop order: gauge field theories
E. W. Dias, A. P. Baeta Scarpelli, L. C. T. Brito +2
We extend a constrained version of Implicit Regularization (CIR) beyond one loop order for gauge field theories. In this framework, the ultraviolet content of the model is displaye…
