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…
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…
A violation of the covariant entropy bound?
Ali Masoumi, Samir D. Mathur
Several arguments suggest that the entropy density at high energy density should be given by the expression , where is a constant of order unity. On the othe…
An equation of state in the limit of high densities
Ali Masoumi, Samir D. Mathur
We take string theory in a box of volume , and ask for the entropy . We let exceed the value corresponding to the largest black hole that can fit in the box…
Bubble Nucleation of Spatial Vector Fields
Ali Masoumi, Xiao Xiao, I-Sheng Yang
We study domain-walls and bubble nucleation in a non-relativistic vector field theory with different longitudinal and transverse speeds of sound. We describe analytical and numeric…
