Generalized Ashtekar variables for Palatini f(R) models
Flavio Bombacigno, Simon Boudet, Giovanni Montani
We consider special classes of Palatini f(R) theories, featured by additional Loop Quantum Gravity inspired terms, with the aim of identifying a set of modified Ashtekar canonical…
Scalar modes in extended hybrid metric-Palatini gravity: weak field phenomenology
Flavio Bombacigno, Fabio Moretti, Giovanni Montani
We investigate the nature of additional scalar degrees of freedom contained in extended hybrid metric-Palatini gravity, outlining the emergence of two coupled dynamical scalar mode…
Gauge invariant formulation of gravitational waves in metric gravity
Fabio Moretti, Flavio Bombacigno, Giovanni Montani
We analyze the gravitational waves propagation in metric theories of gravity. In particular, adopting a gauge invariant formalism we clearly determine the exact propagating…
