Semiclassical (Quantum Field Theory) and Quantum (String) de Sitter Regimes: New Results
A. Bouchareb, M. Ramon Medrano, N. G. Sanchez
We compute the quantum string entropy S_s(m, H) from the microscopic string density of states rho_s (m,H) of mass m in de Sitter space-time. We find for high m, a {\bf new} phase t…
Quantum corrections to the inflaton potential and the power spectra from superhorizon modes and trace anomalies
D. Boyanovsky, H. J. de Vega, N. G. Sanchez
We obtain the effective inflaton potential during slow roll inflation by including the one loop quantum corrections to the energy momentum tensor from scalar curvature and tensor p…
Clarifying Inflation Models: Slow-roll as an expansion in 1/N_{efolds}
D. Boyanovsky, H. J. de Vega, N. G. Sanchez
Slow-roll inflation is studied as an effective field theory.We find as consistent form of the inflaton potential V(phi)=N M^4 w(phi/[sqrt{N}M_P]) where phi is the inflaton field, M…
The Classical and Quantum Inflaton: the Precise Inflationary Potential and Quantum Inflaton Decay after WMAP
D. Boyanovsky, H. J. de Vega, N. G. Sanchez
We clarify classical inflaton models by considering them as effective field theories `a la Ginzburg-Landau. In this approach, the WMAP statement excluding the pure phi^4 potential…
Quantum corrections to slow roll inflation and new scaling of superhorizon fluctuations
D. Boyanovsky, H. J. de Vega, N. G. Sanchez
Precise cosmological data from WMAP and forthcoming CMB experiments motivate the study of the quantum corrections to the slowroll inflationary parameters.We find the quantum (loop)…
