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 can reverse the direction of the one-particle-exchange (OPE) force at long distance if (and under general assumptions, only if)…
A Note on Invariant Measure on the Local Gauge Group
Wei-Min Sun, Xiang-Song Chen, Fan Wang
In this paper we investigated the problem of the existence of invariant meaures on the local gauge group. We prove that it is impossible to define a {\it finite} translationally in…
A simple proof that does not have a Haar measure
Wei-Min Sun, Xiang-Song Chen, Fan Wang
We give a simple proof that there does not exist a Haar measure on the group .
A Note on Functional Integral over the Local Gauge Group
Wei-Min Sun, Xiang-Song Chen, Fan Wang
We evaluated some particular type of functional integral over the local gauge group C^{\infty}({\bf R}^n, U(1)) by going to a discretized lattice. The results explicitly violates t…
Some Problems in Defining Functional Integration over the Gauge Group
Wei-Min Sun, Xiang-Song Chen, Fan Wang
We find that sometimes the usual definition of functional integration over the gauge group through limiting process may have internal difficulties.
