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…
Towards observable signatures of other bubble universes II: Exact solutions for thin-wall bubble collisions
Anthony Aguirre, Matthew C Johnson
We assess the effects of a collision between two vacuum bubbles in the thin-wall limit. After describing the outcome of a generic collision possessing the expected hyperbolic symme…
Towards observable signatures of other bubble universes
Anthony Aguirre, Matthew C Johnson, Assaf Shomer
We evaluate the possibility of observable effects arising from collisions between vacuum bubbles in a universe undergoing false-vacuum eternal inflation. Contrary to conventional w…
Measures on transitions for cosmology from eternal inflation
Anthony Aguirre, Steven Gratton, Matthew C Johnson
We argue that in the context of eternal inflation in the landscape, making predictions for cosmological -- and possibly particle physics -- observables requires a measure on the po…
