Interessi di ricerca 

Modified Gravity The goal of modified gravity is to explain the current accelerated expansion of the Universe and its initial inflationary phase. In order to do so, the Einstein theory of general relativity is implemented with fundamental fields. One possibility is that this field is nothing but the Higgs boson and this idea turns out to yield a phenomenologically viable theory of inflation. Currently, I am trying to show that this very same model might produce also dark energy, namely the source of the current acceleration of the Universe. Theories of modified gravity will be put at test in 2020 when the Euclid mission will be launched. I am a member of the Euclid Theory Working Group and within this collaboration I am working on modeling viable theories of dark energy. Analog Models of Gravity There is a surprising analogy between photons traveling on curved space and phonons (quantized sound excitations) traveling in a perfect fluid, like a BoseEinstein condensate. In particular, it is possible, at least in principle, to create "sound horizons" that surround regions where phonons cannot escape. Theoretical predictions show that these sound horizons should emit a thermal spectrum of phonons, exactly like an astrophysical black hole horizon emit particles in the form of the famous Hawking radiation. This is just one of the many effects that could be observed in a BEC and that are analogous to effects arising from the physics of quantum fields on curved spacetme. Since the latter are very difficult to observe, the analogy could open the way to interesting insights since experiments seem to be at hand. Quantum Gravity The quantization of the gravitational interactions is a very old problem. All the known quantization schemes fail when applied to gravity, mainly because the theory as it is appears to be nonrenormlizable. There are however approaches that can reveal some useful information like the semiclassical one. In this method, fields are quantized on a classical curved geometry and also renormalized with particular techiniques. Another approach is to assume that quantum fields do not commute at very high energy / short distances so that ultraviolet divergences are removed by construction.
