Cosmic Acceleration and Turns in the Swampland
Julian Freigang, Dieter Lust, Guo-En Nian +1
We argue that field trajectories, which lead to cosmic acceleration and feature rapid turns near the boundary of the moduli space, are in the Swampland. We obtain this result by as…
Gradient flow of Einstein-Maxwell theory and Reissner-Nordström black holes
Davide De Biasio, Julian Freigang, Dieter Lust +1
Ricci flow is a natural gradient flow of the Einstein-Hilbert action. Here we consider the analog for the Einstein-Maxwell action, which gives Ricci flow with a stress tensor contr…
Geometric flow equations for the number of space-time dimensions
Davide De Biasio, Julian Freigang, Dieter Lust
In this paper we consider new geometric flow equations, called D-flow, which describe the variation of space-time geometries under the change of the number of dimensions. The D-flo…
