Inflation in scale-invariant theories of gravity
Massimiliano Rinaldi, Guido Cognola, Luciano Vanzo +1
Thanks to the Planck Collaboration, we know the value of the scalar spectral index of primordial fluctuations with unprecedented precision. In addition, the joint analysis of the d…
Reconstructing the inflationary from observations
Massimiliano Rinaldi, Guido Cognola, Luciano Vanzo +1
The BICEP2 collaboration has recently released data showing that the scalar-to-tensor ratio is much larger than expected. The immediate consequence, in the context of gr…
Λ may not be vacuum energy, after all
Luciano Vanzo
We suggest the possibility that the mysterious dark energy component driving the acceleration of the Universe is the leading term, in the de Sitter temperature, of the free energy…
Vacuum fluctuation of conformally coupled scalar field in FLRW space-times
Giovanni Acquaviva, Luca Bonetti, Luciano Vanzo +1
The regularized vacuum fluctuation related to a conformally coupled massless scalar field defined on a space-time with dynamical horizon is computed with respect a radially moving…
