Evaluating Critical Exponents in the Optimized Perturbation Theory
Marcus Benghi Pinto, Rudnei O. Ramos, Paulo J. Sena
We use the optimized perturbation theory, or linear delta expansion, to evaluate the critical exponents in the critical 3d O(N) invariant scalar field model. Regarding the implemen…

Dynamics of Interacting Scalar Fields in Expanding Space-Time
Arjun Berera, Rudnei O. Ramos
The effective equation of motion is derived for a scalar field interacting with other fields in a Friedman-Robertson-Walker background space-time. The dissipative behavior reflecte…
