In this paper we consider cosmological scaling solutions in general relativity coupled to scalar fields with a non-trivial moduli space metric. We discover that the scaling property of the cosmology is synonymous with the scalar fields tracing out a... Read More about Scaling solutions and geodesics in moduli space.

The Dynamics of coset dimensional reduction (2006)
Journal Article
Karthauser, J. L., & Saffin, P. M. (2006). The Dynamics of coset dimensional reduction. Physical Review D, 73(8), https://doi.org/10.1103/PhysRevD.73.084027

The evolution of multiple scalar fields in cosmology has been much studied, particularly when the potential is formed from a series of exponentials. For a certain subclass of such systems it is possible to get `assisted` behaviour, where the presence... Read More about The Dynamics of coset dimensional reduction.
