On Gaussian Random Supergravity

Bachlechner, Thomas C.

Understand

We study the distribution of metastable vacua and the likelihood of slow roll inflation in high dimensional random landscapes.

  • We consider two examples of landscapes: a Gaussian random potential and an effective supergravity potential defined via a Gaussian random superpotential and a trivial K\"ahler potential.
  • To examine these landscapes we introduce a random matrix model that describes the correlations between various derivatives and we propose an efficient algorithm that allows for a numerical study of high dimensional random fields.
  • Using these novel tools, we find that the vast majority of metastable critical points in $N$ dimensional random supergravities are either approximately supersymmetric with $|F|\ll M_{\text{susy}}$ or supersymmetric.
