Probabilities in the inflationary multiverse.

Probabilities in the inflationary multiverse. - 131 p.

Thesis (Ph.D.)--Tufts University, 2006.

Inflationary cosmology leads to the picture of a "multiverse," involving an infinite number of post-inflationary thermalized regions, called pocket universes. In the context of theories with many vacua (pockets), such as the landscape of string theory, the effective constants of Nature may take on different values in different vacua. We propose a method for determining the relative abundances of different types of pocket universes. This is the first prescription which is not plagued by ambiguous gauge-dependencies and does not depend on arbitrary initial conditions.

520 $a Inflationary cosmology leads to the picture of a "multiverse," involving an infinite number of post-inflationary thermalized regions, called pocket universes. In the context of theories with many vacua (pockets), such as the landscape of string theory, the effective constants of Nature may take on different values in different vacua. We propose a method for determining the relative abundances of different types of pocket universes. This is the first prescription which is not plagued by ambiguous gauge-dependencies and does not depend on arbitrary initial conditions.
520 $a Using this prescription, we investigate the volume distribution for the cosmological constant Λ in the context of the Bousso-Polchinski and the Arkani-Hamed-Dimopolous-Kachru landscape models. We find that the resulting distributions have a staggered appearance which is in sharp contrast to the heuristically expected flat distribution. To reconcile our staggered distributions with observations for Λ, these models would have to produce a huge number of vacua in the anthropic range DeltaΛA of Λ, so that the distribution could conceivably become smooth after averaging over some suitable scale deltaΛ << DeltaΛ A.
