Axial Vector Coupling and Chiral Anomaly in the Spectral Quark Model
L. C. Ferreira, A. L. Mota
We studied the Adler-Bardeen-Bell-Jackiw anomaly in the context of a finite chiral quark model known as the Spectral Quark Model. Within this model, we obtain the general non-local…
Asymmetrically Doped Polyacetylene
Heron Caldas
Doped one-dimensional (1D) conjugated polymers, such as polyacetylene, have a conductivity of some metals, like copper. We show that when this polymer is asymmetrically doped, unex…
Effectively irreversible fringe contrast attenuation induced by one degree of freedom
A. R. Bosco de Magalhães, Adélcio C. Oliveira
The attenuation of fringe contrast in a Ramsey interferometer induced by the atom-field interaction is analyzed. We show that short-time power series expansion is not the proper to…
Contact process on a Voronoi triangulation
Marcelo M. de Oliveira, S. G. Alves, S. C. Ferreira +1
We study the continuous absorbing-state phase transition in the contact process on the Voronoi-Delaunay lattice. The Voronoi construction is a natural way to introduce quenched coo…
Critical Dopant Concentration in Polyacetylene and Phase Diagram from a Continuous Four-Fermi Model
Heron Caldas, Jean-Loic Kneur, Marcus B. Pinto +1
The Optimized Perturbation Theory (OPT) method, at finite temperature and finite chemical potential, is applied to the field theory model for polyacetylene. The critical dopant con…
Temperature Effects in a Fermi Gas with Population Imbalance
Heron Caldas, A. L. Mota
We investigate temperature effects in a Fermi gas with imbalanced spin populations. From the general expression of the thermal gap equation we find, in {\it weak coupling limit}, a…
