Quantized Dirac Fields in torsionful gravity: cosmological implications and links with the dark universe
Antonio Capolupo, Sante Carloni, Luca Fabbri +3
We consider a classical field in square torsion theory as a source of torsion for a quantum fermion field in FLRW metric. In the framework of QFT, we obtain vacuum contributions to…
Matter couplings in Horava-Lifshitz and their cosmological applications
Sante Carloni, Emilio Elizalde, Pedro J. Silva
In this paper, the issue how to introduce matter in Hořava-Lifshitz theories of gravity is addressed. This is a key point in order to complete the proper definition of these theori…
Modified first-order Horava-Lifshitz gravity: Hamiltonian analysis of the general theory and accelerating FRW cosmology in power-law F(R) model
Sante Carloni, Masud Chaichian, Shin'ichi Nojiri +3
We propose the most general modified first-order Hořava-Lifshitz (HL) gravity, whose action does not contain time derivatives higher than the second order. The Hamiltonian structur…
An analysis of the phase space of Horava-Lifshitz cosmologies
Sante Carloni, Emilio Elizalde, Pedro J. Silva
Using the dynamical system approach, properties of cosmological models based on the Horava-Lifshitz gravity are systematically studied. In particular, the cosmological phase space…
Neutrino mixing as a source for cosmological constant
Massimo Blasone, Antonio Capolupo, Salvatore Capozziello +2
We report on recent results showing that neutrino mixing may lead to a non-zero contribution to the cosmological constant. This contribution is of a completely different nature wit…
Neutrino mixing and cosmological constant
Massimo Blasone, Antonio Capolupo, Salvatore Capozziello +2
We report on the recent result that the non--perturbative vacuum structure associated with neutrino mixing leads to a non--zero contribution to the value of the cosmological consta…
