This paper extends a recent investigation of the string theory landscape (Ceresole et al 2006 Phys. Rev. D 74 086010), where it was found that the decay rate of de Sitter (dS) vacua to a collapsing space with a negative vacuum energy can be quite large. The parts of space that experience a decay to a collapsing space, or to a Minkowski vacuum, never return back to dS space. The channels of irreversible vacuum decay serve as sinks for the probability flow. The existence of such sinks is a… Expand

Disorder on the landscape
Disorder on the string theory landscape may significantly affect dynamics of eternal inflation leading to the possibility for some vacua on the landscape to become dynamically preferable over others.… Expand
Boltzmann brains and the scale-factor cutoff measure of the multiverse
To make predictions for an eternally inflating 'multiverse', one must adopt a procedure for regulating its divergent spacetime volume. Recently, a new test of such spacetime measures has emerged:… Expand
De Sitter Space Without Dynamical Quantum Fluctuations
We argue that, under certain plausible assumptions, de Sitter space settles into a quiescent vacuum in which there are no dynamical quantum fluctuations. Such fluctuations require either an evolving… Expand
Neutrino Masses in the Landscape and Global-Local Dualities in Eternal Inflation
Author(s): Mainemer Katz, Dan | Advisor(s): Bousso, Raphael | Abstract: In this dissertation we study two topics in Theoretical Cosmology: one more formal, the other more phenomenological. We work in… Expand
Island cosmology in the landscape
Abstract In the eternally inflationary background driven by the metastable vacua of the landscape, it is possible that some local quantum fluctuations with the null energy condition violation can be… Expand
Classical and Quantum Aspects of Anisotropic Cosmology
The idea that our observable Universe may have originated from a quantum tunneling event out of an eternally inflating false vacuum state is a cornerstone of the multiverse paradigm. Modern theories… Expand
De Sitter Space Without Quantum Fluctuations
We argue that, under certain plausible assumptions, de Sitter space settles into a quiescent vacuum in which there are no quantum fluctuations. Quantum fluctuations require time-dependent histories… Expand
A pr 2 00 8 Boltzmann babies in the proper time measure
After commenting briefly on the role of the typicality assumption in science , we advocate a phenomenological approach to the cosmological measure problem. Like any other theory, a measure should be… Expand
Predicting the cosmological constant with the scale-factor cutoff measure
It is well known that anthropic selection from a landscape with a flat prior distribution of cosmological constant {lambda} gives a reasonable fit to observation. However, a realistic model of the… Expand

Taming the Runaway Problem of Inflationary Landscapes
A wide variety of vacua, and their cosmological realization, may provide an explanation for the apparently anthropic choices of some parameters of particle physics and cosmology. If the probability… Expand
Domain walls, near-BPS bubbles, and probabilities in the landscape
We develop a theory of static BPS domain walls in stringy landscape and present a large family of BPS walls interpolating between different supersymmetric vacua. Examples include KKLT models, STU… Expand
Probabilities in the landscape: The decay of nearly flat space
We discuss aspects of the problem of assigning probabilities in eternal inflation. In particular, we investigate a recent suggestion that the lowest energy de Sitter vacuum in the landscape is… Expand
Density perturbations and the cosmological constant from inflationary landscapes
An anthropic understanding of the cosmological constant requires that the vacuum energy at late time scans from one patch of the universe to another. If the vacuum energy during inflation also scans,… Expand
Cosmological constant and the time of its dominance
We explore a model in which the cosmological constant L and the density contrast at the time of recombination s rec are random variables, whose range and a priori probabilities are determined by the… Expand

TLDR
The picture that has emerged from this line of development is that a small closed universe can spontaneously nucleate out of nothing, where by ‘nothing’ I mean a state with no classical space and time. Expand

TLDR
It is shown here that a nonminimal conformal coupling of the inflaton to the curvature scalar, as well as radiative corrections to the effective potential, may provide a dynamical cutoff and generate stationary solutions for chaotic inflation potentials. Expand
Likely Values of the Cosmological Constant
In theories in which the cosmological constant takes a variety of values in different "subuniverses," the probability distribution of its observed values is conditioned by the requirement that there… Expand
What does inflation really predict
If the inflaton potential has multiple minima, as may be expected in, e.g., the string theory 'landscape', inflation predicts a probability distribution for the cosmological parameters describing… Expand
Solutions to the cosmological constant problems
We critically review several recent approaches to solving the two cosmological constant problems. The "old" problem is the discrepancy between the observed value of $\Lambda$ and the large values… Expand
