Co-existence of Gravity and Antigravity: The Unification of Dark Matter and Dark Energy

Xiang-Song Chen

Massive gravity with second and fourth derivatives is shown to give both attractive and repulsive gravities. In contrast to the attractive gravity correlated with the energy-moment…

Reverse the force direction at long distance by a running coupling

Xiang-Song Chen

We reveal that a suitable running coupling $α (q^{2})$ can reverse the direction of the one-particle-exchange (OPE) force at long distance if (and under general assumptions, only if)…
