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…

Asymptotically Improved Convergence of Optimized Perturbation Theory in the Bose-Einstein Condensation Problem
Jean-Loic Kneur, Marcus B. Pinto, Rudnei O. Ramos
We investigate the convergence properties of optimized perturbation theory, or linear expansion (LDE), within the context of finite temperature phase transitions. Our results p…
