Kink Collisions in Curved Field Space
Pontus Ahlqvist, Kate Eckerle, Brian Greene
We study bubble universe collisions in the ultrarelativistic limit with the new feature of allowing for nontrivial curvature in field space. We establish a simple geometrical inter…
Bubble Universe Dynamics After Free Passage
Pontus Ahlqvist, Kate Eckerle, Brian Greene
We consider bubble collisions in single scalar field theories with multiple vacua. Recent work has argued that at sufficiently high impact velocities, collisions between such bubbl…
Exploring Spiral Inflation in String Theory
Pontus Ahlqvist, Brian Greene, David Kagan
We investigate the possibility that spiral inflation can be realized using the near-conifold flux potentials for the complex structure moduli in type IIB string theory compactified…
Warped Vacuum Statistics
Pontus Ahlqvist, Brian R. Greene, David Kagan
We consider the effect of warping on the distribution of type IIB flux vacua constructed with Calabi-Yau orientifolds. We derive an analytical form of the distribution that incorpo…
Conifolds and Tunneling in the String Landscape
Pontus Ahlqvist, Brian R. Greene, David Kagan +3
We investigate flux vacua on a variety of one-parameter Calabi-Yau compactifications, and find many examples that are connected through continuous monodromy transformations. For th…
