Palatini formulation of modified gravity with a nonminimal curvature-matter coupling [PDF]

open access: yes, 2011
We derive the field equations and the equations of motion for massive test particles in modified theories of gravity with an arbitrary coupling between geometry and matter by using the Palatini formalism.

f(R,L_m) gravity [PDF]

open access: yes, 2010
We generalize the $f(R)$ type gravity models by assuming that the gravitational Lagrangian is given by an arbitrary function of the Ricci scalar $R$ and of the matter Lagrangian $L_m$.

Galactic rotation curves in modified gravity with non-minimal coupling between matter and geometry [PDF]

open access: yes, 2010
We investigate the possibility that the behavior of the rotational velocities of test particles gravitating around galaxies can be explained in the framework of modified gravity models with non-minimal matter-geometry coupling. Generally, the dynamics of

f(R,T) gravity [PDF]

open access: yes, 2011
We consider f(R,T) modified theories of gravity, where the gravitational Lagrangian is given by an arbitrary function of the Ricci scalar R and of the trace of the stress-energy tensor T.
