On the unlikeliness of multi-field inflation: bounded random potentials and our vacuum
On the unlikeliness of multi-field inflation: bounded random potentials and our vacuum
Based on random matrix theory, we compute the likelihood of saddles and minima in a class of random potentials that are softly bounded from above and below, as required for the validity of low energy effective theories. Imposing this bound leads to a random mass matrix with non-zero mean of …
