The distribution of Omega_k from the scale-factor cutoff measure
Andrea De Simone, Michael P. Salem
Our universe may be contained in one among a diverging number of bubbles that nucleate within an eternally inflating multiverse. A promising measure to regulate the diverging space…
Transdimensional Tunneling in the Multiverse
Jose J. Blanco-Pillado, Delia Schwartz-Perlov, Alexander Vilenkin
Topology-changing transitions between vacua of different effective dimensionality are studied in the context of a 6-dimensional Einstein-Maxwell theory. The landscape of this theor…
Kahler Moduli Inflation Revisited
Jose J. Blanco-Pillado, Duncan Buck, Edmund J. Copeland +2
We perform a detailed numerical analysis of inflationary solutions in Kahler moduli of type IIB flux compactifications. We show that there are inflationary solutions even when all…
Holographic multiverse and conformal invariance
Jaume Garriga, Alexander Vilenkin
We consider a holographic description of the inflationary multiverse, according to which the wave function of the universe is interpreted as the generating functional for a lower d…
Quantum Tunneling in Flux Compactifications
Jose J. Blanco-Pillado, Delia Schwartz-Perlov, Alexander Vilenkin
We identify instantons representing vacuum decay in a 6-dimensional toy model for string theory flux compactifications, with the two extra dimensions compactified on a sphere. We e…
Negative vacuum energy densities and the causal diamond measure
Michael P. Salem
Arguably a major success of the landscape picture is the prediction of a small, non-zero vacuum energy density. The details of this prediction depends in part on how the diverging…
