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…
Semiclassical (QFT) and Quantum (String) anti - 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 of mass m in Anti de Sitter space-time. For high m, (high Hm -->c/α'), no phase transi…
The SL(2,R)WZWN string model as a deformed oscillator and its classical-quantum string regimes
M. Ramon Medrano, N. G. Sanchez
We study the SL(2,R) WZWN string model describing bosonic string theory in AdS_3 space-time as a deformed oscillator together with its mass spectrum and the string modified SL(2,R)…
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…
