Applicability of the Linear delta Expansion for the lambda phi^4 Field Theory at Finite Temperature in the Symmetric and Broken Phases
R. L. S. Farias, G. Krein, R. O. Ramos
The thermodynamics of a scalar field with a quartic interaction is studied within the linear delta expansion (LDE) method. Using the imaginary-time formalism the free energy is eva…
Warm Inflation and its Microphysical Basis
Arjun Berera, Ian G. Moss, Rudnei O. Ramos
The microscopic quantum field theory origins of warm inflation dynamics are reviewed. The warm inflation scenario is first described along with its results, predictions and compari…
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…
