Counting Vacua in Random Landscapes
Richard Easther, Alan H. Guth, Ali Masoumi
It is speculated that the correct theory of fundamental physics includes a large landscape of states, which can be described as a potential which is a function of N scalar fields a…
Auxiliary variables for nonlinear equations with softly broken symmetries
Ken. D. Olum, Ali Masoumi
General methods of solving equations deal with solving N equations in N variables and the solutions are usually a set of discrete values. However, for problems with a softly broken…
Efficient numerical solution to vacuum decay with many fields
Ali Masoumi, Ken D. Olum, Benjamin Shlaer
Finding numerical solutions describing bubble nucleation is notoriously difficult in more than one field space dimension. Traditional shooting methods fail because of the extreme n…
Solitons in generalized galileon theories
Mariana Carrillo-Gonzalez, Ali Masoumi, Adam R. Solomon +1
We consider the existence and stability of solitons in generalized galileons, scalar field theories with higher-derivative interactions but second-order equations of motion. It has…
Tunneling from a Minkowski vacuum to an AdS vacuum: A new thin-wall regime
Ali Masoumi, Sonia Paban, Erick J. Weinberg
Using numerical and analytic methods, we study quantum tunneling from a Minkowski false vacuum to an anti-de Sitter true vacuum. Scanning the parameter space of theories with quart…
Vacuum statistics and stability in axionic landscapes
Ali Masoumi, Alexander Vilenkin
We investigate vacuum statistics and stability in random axionic landscapes. For this purpose we developed an algorithm for a quick evaluation of the tunneling action, which in mos…
