The Perturbative Gross Neveu Model Coupled to a Chern-Simons Field: A Renormalization Group Study
V. S. Alves, M. Gomes, S. V. L. Pinheiro +1
In 2+1 dimensions, for low momenta, using dimensional renormalization we study the effect of a Chern-Simons field on the perturbative expansion of fermions self interacting through…
Retarded Greens Functions and Forward Scattering Amplitudes in Thermal Field Theory
F. T. Brandt, Ashok Das, J. Frenkel +1
In this paper, we give a simple diagrammatic identification of the unique combination of the causal n-point vertex functions in the real time formalism that would coincide with the…
On the Nonabelian Aharonov Bohm Scattering of Spinless Particles
M. Gomes, L. C. Malacarne, A. J. da Silva
The Aharonov Bohm scattering for spinless, isospin 1/2, particles interacting through a nonabelian Chern-Simons field is studied. Starting from the relativistic quantum field theor…
Exact Effective Action for (1+1 Dimensional) Fermions in an Abelian Background at Finite Temperature
Ashok Das, A. J. da Silva
In an effort to further understand the structure of effective actions for fermions in an external gauge background at finite temperature, we study the example of 1+1 dimensional fe…
Nonrelativistic Limit of the Scalar Chern-Simons Theory and the Aharonov-Bohm Scattering
M. Gomes, J. M. C. Malbouisson, A. J. da Silva
We study the nonrelativistic limit of the quantum theory of a Chern-Simons field minimally coupled to a scalar field with quartic self-interaction. The renormalization of the relat…
