Non-minimal curvature-matter couplings in modified gravity
Published 18 Nov 2008 in gr-qc | (0811.2876v1)
Abstract: Recently, in the context of f(R) modified theories of gravity, it was shown that a curvature-matter coupling induces a non-vanishing covariant derivative of the energy-momentum, implying non-geodesic motion and, under appropriate conditions, leading to the appearance of an extra force. We study the implications of this proposal and discuss some directions for future research.
