Quantum corrections for the phase diagram of systems with competing order
N. L. Silva Júnior, Mucio A. Continentino, Daniel G. Barci
We use the effective potential method of quantum field theory to obtain the quantum corrections to the zero temperature phase diagram of systems with competing order parameters. We…
Long range interactions and the 3D asymptotic fermion spectrum
Daniel G. Barci, Luis E. Oxman
In this article, we study the stability of the space of asymptotic fermion states in (2+1)D, when long range interparticle interactions are present. This is done in the framework o…
Universal Properties in Low Dimensional Fermionic Systems and Bosonization
L. E. Oxman, D. G. Barci, E. R. Mucciolo
We analyze the universal transport behavior in 1D and 2D fermionic systems by following the unified framework provided by bosonization. The role played by the adiabatic transition…
Topological and Universal Aspects of Bosonized Interacting Fermionic Systems in (2+1)d
D. G. Barci, L. E. Oxman, S. P. Sorella
General results on the structure of the bosonization of fermionic systems in d are obtained. In particular, the universal character of the bosonized topological current is e…
Three dimensional fermionic determinants, Chern-Simons and nonlinear field redefinitions
D. G. Barci, V. E. R. Lemes, C. Linhares de Jesus +3
The three dimensional abelian fermionic determinant of a two component massive spinor in flat euclidean space-time is resetted to a pure Chern-Simons action through a nonlinear red…
Asymptotic States in Non-Local Field Theories
D. G. Barci, L. E. Oxman
Asymptotic states in field theories containing non-local kinetic terms are analyzed using the canonical method, naturally defined in Minkowski space. We apply our results to study…
