Cosmological Unparticle Correlators
G. L. Alberghi, A. Yu. Kamenshchik, A. Tronconi +2
We introduce and study an extension of the correlator of unparticle matter operators in a cosmological environment. Starting from FRW spaces we specialize to a de Sitter spacetime…
Dark Energy, Induced Gravity and Broken Scale Invariance
F. Finelli, A. Tronconi, G. Venturi
We study the cosmological evolution of an induced gravity model with a self-interacting scalar field and in the presence of matter and radiation. Such model leads to Einstein G…
Inflation and the semiclassical dynamics of a conformal scalar field
G. L. Alberghi, C. Appignani, R. Casadio +2
We derive the semiclassical evolution of massless conformally coupled scalar matter in the de Sitter space-time from the Born-Oppenheimer reduction of the Wheeler-DeWitt equation.…
