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…

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…
