CMB quadrupole suppression: I. Initial conditions of inflationary perturbations

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

We investigate the issue of initial conditions of curvature and tensor perturba- tions at the beginning of slow roll inflation and their effect on the power spectra. Renormalizabil…

CMB quadrupole suppression: II. The early fast roll stage

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

Within the effective field theory of inflation, an initialization of the classical dynamics of the inflaton with approximate equipartition between the kinetic and potential energy…

Single Field Inflation models allowed and ruled out by the three years WMAP data

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

We study the single field slow-roll inflation models that better fit the available CMB and LSS data including the three years WMAP data: new inflation and hybrid inflation. We stud…

Self-Gravitating Phase Transitions: Point Particles, Black Holes and Strings

Norma G. Sanchez

We compute the quantum string entropy S_s(m,j) of the microscopic string states of mass m and spin j in two physically relevant backgrounds: Kerr (rotating) black holes and de Sitt…

Clarifying Slow Roll Inflation and the Quantum Corrections to the Observable Power Spectra

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

Slow-roll inflation can be studied as an effective field theory. The form of the inflaton potential consistent with the data is V(phi) = N M^4 w(phi/[sqrt{N} M_{Pl}]) where phi is…
