Non-topological fractional fermion number in the Jackiw-Rossi model
Caio Almeida, Alberto Alonso-Izquierdo, Rodrigo Fresneda +2
We compute the vacuum fermion current in dimensional Jackiw-Rossi model by using the expansion. The current is expressed through a weighted -function with a matrix…

Radiatively induced finite and (un)determined Chern-Simons-like terms
E. Passos, K. E. L. de farias, M. A. Anacleto +2
The problem of Chern-Simons-like term induction via quantum corrections in four-dimensions is investigated in two different cases. In the first case, we consider two distinct appro…
