Condensation of Vortex-Strings: Effective Potential Contribution Through Dual Actions
Rudnei O. Ramos, J. F. Medeiros Neto, Daniel G. Barci +1
Topological excitations are believed to play an important role in different areas of physics. For example, one case of topical interest is the use of dual models of quantum cromody…

The point-splitting regularization of (2+1)d parity breaking models
D. G. Barci, J. F. Medeiros Neto, L. E. Oxman +1
The coefficient of the Chern-Simons term in the effective action for massive Dirac fermions in three dimensions is computed by using the point-splitting regularization method. We s…
