修正引力中的非最小曲率-物质耦合

Non-minimal curvature-matter couplings in modified gravity

Orfeu Bertolami, Tiberiu Harko, Francisco S. N. Lobo, Jorge Páramos

摘要:

最近,在f(R)修正引力理论的背景下,人们发现曲率-物质耦合会导致能量-动量的非零协变导数,这意味着非测地线运动,在适当的条件下,会导致额外力的出现。我们研究了这一建议的影响,并讨论了未来的研究方向。

英文摘要:

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.
