Hints of (trans-Planckian) asymptotic freedom in semiclassical cosmology
Corrado Appignani, Roberto Casadio
We employ the semiclassical approximation to the Wheeler-DeWitt equation in the spatially flat de Sitter Universe to investigate the dynamics of a minimally coupled scalar field ne…

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.…

QCD Universality recovered via the Total Available Quadri-Scalar: Atot
Corrado Appignani
After presenting a brief review of the phenomenology of the Leading Effect, we define a new variable, the ``Total Available Quadri-Scalar'' (Atot), and propose it as the invariant…
