Non-Uniqueness of Classical Inflationary Trajectories on a High-Dimensional Landscape

Understand

Motivated by the string landscape, inflation may happen on a high dimensional complicated potential.

• We propose a new way to construct some high dimensional random potentials, and study inflation on top of that, for up to 50-dimensions in field space.
• Especially, random bifurcations of classical inflationary trajectory are studied.
• It is shown that the bifurcation probability increases as a function of number of dimensions.
