Multi-graviton theory from a discretized RS brane-world and the induced cosmological constant
Guido Cognola, Emilio Elizalde, Shin'ichi Nojiri +2
We propose a multi-graviton theory with non-nearest-neighbor couplings in the theory space. The resulting four-dimensional discrete mass spectrum reflects the structure of a lattic…
One-loop effective potential from higher-dimensional AdS black holes
Guido Cognola, Emilio Elizalde, Sergio Zerbini
We study the quantum effects in a brane-world model in which a positive constant curvature brane universe is embedded in a higher-dimensional bulk AdS black hole, instead of the us…
Effective action for scalar fields and generalised zeta-function regularisation
Guido Cognola, Sergio Zerbini
Motivated by the study of quantum fields in a Friedman-Robertson-Walker (FRW) spacetime, the one-loop effective action for a scalar field defined in the ultrastatic manifold $R\tim…
