Approximating tunneling rates in multi-dimensional field spaces
Ali Masoumi, Ken D. Olum, Jeremy M. Wachter
Quantum mechanics makes the otherwise stable vacua of a theory metastable through the nucleation of bubbles of the new vacuum. This in turn causes a first order phase transition. T…
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…
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…
State of matter at high density and entropy bounds
Ali Masoumi
Entropy of all systems that we understand well is proportional to their volumes except for black holes given by their horizon area. This makes the microstates of any quantum theory…
