CMB acoustic scale in the entropic-like accelerating universe
Roberto Casadio, Alessandro Gruppuso
We consider generalizations of the entropic accelerating universe recently proposed in Ref. [4,5] and show that their background equations can be made equivalent to a model with a…
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…
On boundary terms and conformal transformations in curved space-times
R. Casadio, A. Gruppuso
We intend to clarify the interplay between boundary terms and conformal transformations in scalar-tensor theories of gravity. We first consider the action for pure gravity in five…
Discrete Symmetries and Localization in a Brane-world
R. Casadio, A. Gruppuso
Discrete symmetries are studied in warped space-times with one extra dimension. In particular, we analyze the compatibility of five- and four-dimensional charge conjugation, parity…
Electromagnetic Contributions to Lepton g-2 in a Thick Brane-World
R. Casadio, A. Gruppuso, G. Venturi
We consider Standard Model fields living inside a thick four dimensional flat brane embedded in a (possibly warped) five dimensional space-time and estimate the electromagnetic cor…
Non-minimally coupled scalar fields in homogeneous universes
G. L. Alberghi, R. Casadio, A. Gruppuso
The equations governing the evolution of non-minimally coupled scalar matter and the scale factor of a Robertson-Walker universe are derived from a minisuperspace action. As for th…
