Is the Equivalence Principle violated by Generalized Uncertainty Principles and Holography in a brane-world?
Fabio Scardigli, Roberto Casadio
It has been recently debated whether a class of generalized uncertainty principles that include gravitational sources of error are compatible with the holographic principle in mode…
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.…
Boundaries and the Casimir effect in non-commutative space-time
Roberto Casadio, Alessandro Gruppuso, Benjamin Harms +1
We calculate modifications to the scalar Casimir force between two parallel plates due to space-time non-commutativity. We devise a heuristic approach to overcome the difficulties…
Non-adiabatic quantum effects from a Standard Model time-dependent Higgs vev
R. Casadio, P. L. Iafelice, G. P. Vacca
We consider the time-dependence of the Higgs vacuum expectation value (vev) given by the dynamics of the Standard Model and study the non-adiabatic production of both bosons and fe…
