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…

Universal Transverse Conductance between Quantum Hall Regions and (2+1)D Bosonization
Daniel G. Barci, L. E. Oxman
Using bosonization techniques for (2+1)D systems, we show that the transverse conductance for a system with general current interactions, when measured between perfect Hall regions…
