Holographic Multiverse [PDF]

open access: greenJournal of Cosmology and Astroparticle Physics, 2009
We explore the idea that the dynamics of the inflationary multiverse is encoded in its future boundary, where it is described by a lower dimensional theory which is conformally invariant in the UV.

Is the Quilted Multiverse Consistent with a Thermodynamic Arrow of Time? [PDF]

open access: yesFrontiers in Physics, 2018
Theoretical achievements, as well as much controversy, surround multiverse theory. Various types of multiverses, with an increasing amount of complexity, were suggested and thoroughly discussed in literature by now.

Vacuum decay in an interacting multiverse [PDF]

open access: yesPhysics Letters B, 2016
We examine a new multiverse scenario in which the component universes interact. We focus our attention to the process of “true” vacuum nucleation in the false vacuum within one single element of the multiverse. It is shown that the interactions lead to a

MultiVERSE: a multiplex and multiplex-heterogeneous network embedding approach

open access: yesScientific Reports, 2021
Network embedding approaches are gaining momentum to analyse a large variety of networks. Indeed, these approaches have demonstrated their effectiveness in tasks such as community detection, node classification, and link prediction.

Multiverse Predictions for Habitability: Fraction of Planets that Develop Life

open access: yesUniverse, 2019
In a multiverse context, determining the probability of being in our particular universe depends on estimating its overall habitability compared to other universes with different values of the fundamental constants.

Asymptotically Vanishing Cosmological Constant in the Multiverse [PDF]

open access: green, 2011
We study the problem of the cosmological constant in the context of the multiverse in Lorentzian spacetime, and show that the cosmological constant will vanish in the future.

The Static Quantum Multiverse

open access: hybrid, 2012
We consider the multiverse in the intrinsically quantum mechanical framework recently proposed in Refs. [1,2]. By requiring that the principles of quantum mechanics are universally valid and that physical predictions do not depend on the reference frame ...

Past incompleteness of a bouncing multiverse [PDF]

open access: hybrid, 2014
According to classical GR, Anti-de Sitter (AdS) bubbles in the multiverse terminate in big crunch singularities. It has been conjectured, however, that the fundamental theory may resolve these singularities and replace them by nonsingular bounces.

The data-processing multiverse of event-related potentials (ERPs): A roadmap for the optimization and standardization of ERP processing and reduction pipelines

open access: yesNeuroImage, 2021
In studies of event-related brain potentials (ERPs), numerous decisions about data processing are required to extract ERP scores from continuous data. Unfortunately, the systematic impact of these choices on the data quality and psychometric reliability ...

Possible physical universes [PDF]

open access: yesZagadnienia Filozoficzne w Nauce, 2005
The purpose of this paper is to discuss the various types of physical universe which could exist according to modern mathematical physics. The paper begins with an introduction that approaches the question from the viewpoint of ontic structural realism ...
