Dynamical system analysis of the cosmological phases in Palatini -essence gravity
Fabio Moretti, Flavio Bombacigno
We formulate a generalized -essence model in the presence of a Palatini gravitational sector. In the corresponding biscalar-tensor theory, we discuss the distin…
Reproducing anomalous transport coefficients from electro-static tokamak edge turbulent dynamics
Fabio Moretti, Francesco Cianfrani, Nakia Carlevaro +1
Turbulent transport near the X-point of a large tokamak is examined using local, gradient-driven simulations that determine the saturated plasma profiles. The distribution of a rep…
Gravitational waves in Palatini gravity for a non-minimal geometry-matter coupling
Flavio Bombacigno, Fabio Moretti, Gonzalo J. Olmo
We discuss the propagation of gravitational waves over a non-Riemannian spacetime, when a non-minimal coupling between the geometry and matter is considered in the form of contract…
Turbulent transport regimes in the presence of an X-point magnetic configuration
Fabio Moretti, Nakia Carlevaro, Francesco Cianfrani +1
We analyze the transport properties of the two-dimensional electrostatic turbulence characterizing the edge of a Tokamak device from the study of test particles motion (passive flu…
