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…
