Vacuum decay in multidimensional field landscapes: thin, thick and intersecting walls
Vijay Balasubramanian, Bartlomiej Czech, Klaus Larjo +1
We study tunneling between vacua in multi-dimensional field spaces. Working in the strict thin wall approximation, we find that the conventional instantons for false vacuum decay d…
Twisted Inflation
Joshua L. Davis, Thomas S. Levi, Mark Van Raamsdonk +1
We present a new mechanism for slow-roll inflation based on higher dimensional supersymmetric gauge theory compactified to four dimensions with twisted (supersymmetry breaking) bou…
Bubble, Bubble, Flow and Hubble: Large Scale Galaxy Flow from Cosmological Bubble Collisions
Klaus Larjo, Thomas S. Levi
We study large scale structure in the cosmology of Coleman-de Luccia bubble collisions. Within a set of controlled approximations we calculate the effects on galaxy motion seen fro…
Godel space from wrapped M2-branes
Thomas S. Levi, Joris Raeymaekers, Dieter Van den Bleeken +2
We show that M-theory admits a supersymmetric compactification to the Godel universe of the form Godel3 x S2 x CY3. We interpret this geometry as coming from the backreaction of M2…
Watching Worlds Collide: Effects on the CMB from Cosmological Bubble Collisions
Spencer Chang, Matthew Kleban, Thomas S. Levi
We extend our previous work on the cosmology of Coleman-de Luccia bubble collisions. Within a set of approximations we calculate the effects on the cosmic microwave background (CMB…
When Worlds Collide
Spencer Chang, Matthew Kleban, Thomas S. Levi
We analyze the cosmological signatures visible to an observer in a Coleman-de Luccia bubble when another such bubble collides with it. We use a gluing procedure to generalize the r…
