Multiverse Predictions for Habitability: Planetary Characteristics [PDF]
Universe, 2022 Recent detections of potentially habitable exoplanets around sunlike stars demand increased exploration of the physical conditions that can sustain life, by whatever methods available.

Islands in multiverse models [PDF]
Journal of High Energy Physics, 2021 We consider multiverse models in two-dimensional linear dilaton-gravity theories as toy models of false vacuum eternal inflation. Coupling conformal matter we calculate the Von Neumann entropy of subregions. When these are sufficiently large we find that

Entanglement in a multiverse with no common space-time [PDF]
AIP Conference Proceedings 1514, 31 (2013), 2012 Inter-universal entanglement may even exist in a multiverse in which there is no common space-time among the universes. In particular, the entanglement between the expanding and contracting branches of the universe might have observable consequences in ...

The Copernican Multiverse of Sets [PDF]
The Review of Symbolic Logic, 2020 We develop an untyped framework for the multiverse of set theory. $\mathsf{ZF}$ is extended with semantically motivated axioms utilizing the new symbols $\mathsf{Uni}(\mathcal{U})$ and $\mathsf{Mod}(\mathcal{U, \sigma})$, expressing that $\mathcal{U}$ is a universe and that $\sigma$ is true in the universe $\mathcal{U}$, respectively.

Quantum state of the multiverse [PDF]
Physical Review D, 2011 A third quantization formalism is applied to a simplified multiverse scenario. A well defined quantum state of the multiverse is obtained which agrees with standard boundary condition proposals.

Non-linearities in the quantum multiverse [PDF]
, 2012 It has been recently proposed that the multiverse of eternal inflation and the many-worlds interpretation of quantum mechanics can be identified, yielding a new view on the measure and measurement problems. In the present note, we argue that a non-linear

Physical Review D, 2011 I consider a landscape containing three vacua and study the topology of global spacelike slices in eternal inflation. A discrete toy model, which generalizes the well studied Mandelbrot model, reveals a rich phase structure.

A brief history of the multiverse [PDF]
Reports on Progress in Physics, 2017 The theory of the inflationary multiverse changes the way we think about our place in the world. According to its most popular version, our world may consist of infinitely many exponentially large parts, exhibiting different sets of low-energy laws of ...

Measures for a Transdimensional Multiverse [PDF]
Journal of Cosmology and Astroparticle Physics, 2010 The multiverse/landscape paradigm that has emerged from eternal inflation and string theory, describes a large-scale multiverse populated by "pocket universes" which come in a huge variety of different types, including different dimensionalities.

A dark energy multiverse [PDF]
Classical and Quantum Gravity, 2007 We present cosmic solutions corresponding to universes filled with dark and phantom energy, all having a negative cosmological constant. All such solutions contain infinite singularities, successively and equally distributed along time, which can be either big bang/crunchs or big rips singularities.
