Particle decay during inflation: self-decay of inflaton quantum fluctuations during slow roll

D. Boyanovsky, H. J. de Vega, N. G. Sanchez

Particle decay during inflation is studied by implementing a dynamical renormalization group resummation combined with a small Delta expansion. Delta measures the deviation from th…

The String Phases of Hawking Radiation, De Sitter Stage and De Broglie Type Duality

Marina Ramon Medrano, Norma G. Sanchez

We explicitly describe the last stages of black hole evaporation in the context of string theory : the combined study of Quantum Field Theory (QFT) and String Theory (ST) in curved…

The quantum inflaton, primordial perturbations and CMB fluctuations

F. J. Cao, H. J. de Vega, N. G. Sanchez

We compute the primordial scalar, vector and tensor metric perturbations arising from quantum field inflation. Quantum field inflation takes into account the nonperturbative quantu…
