Noise and Dissipation During Preheating
Sergio E. Joras, Rudnei O. Ramos
We study the consequences of noise and dissipation for parametric resonance during preheating. The effective equations of motion for the inflaton and the radiation field are obtain…
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…
Unusual Transition Patterns in Bose-Einstein Condensation
Marcus B. Pinto, Rudnei O. Ramos, Frederico F. de Souza Cruz
We analyze the possible transition patterns exhibited by an effective non-relativistic field model describing interacting binary homogeneous dilute Bose gases whose overall potenti…
