Surviving the crash: assessing the aftermath of cosmic bubble collisions
Anthony Aguirre, Matthew C Johnson, Martin Tysanner
This paper is the third in a series investigating the possibility that if we reside in an inflationary "bubble universe", we might observe the effects of collisions with other such…
An obstacle to populating the string theory landscape
Matthew C Johnson, Magdalena Larfors
We construct domain walls and instantons in a class of models with coupled scalar fields, determining, in agreement with previous studies, that many such solutions contain naked ti…
Field dynamics and tunneling in a flux landscape
Matthew C Johnson, Magdalena Larfors
We investigate field dynamics and tunneling between metastable minima in a landscape of Type IIB flux compactifications, utilizing monodromies of the complex structure moduli space…
