Neutron stars and the cosmological constant problem [PDF]

open access: yesPhysical Review D, 2011
The gravitational aether theory is a modification of general relativity that decouples vacuum energy from gravity, and thus can potentially address the cosmological constant problem. The classical theory is distinguishable from general relativity only in the presence of relativistic pressure (or vorticity).

Integrating multimodal data and machine learning for entrepreneurship research

open access: yesStrategic Entrepreneurship Journal, EarlyView.
Abstract Research Summary Extant research in neuroscience suggests that human perception is multimodal in nature—we model the world integrating diverse data sources such as sound, images, taste, and smell. Working in a dynamic environment, entrepreneurs are expected to draw on multimodal inputs in their decision making.

The Selfish Higgs

open access: yesJournal of High Energy Physics, 2019
We propose a mechanism to solve the Higgs naturalness problem through a cosmological selection process. The discharging of excited field configurations through membrane nucleation leads to discrete jumps of the cosmological constant and the Higgs mass ...

The quantum vacuum and the cosmological constant problem [PDF]

open access: yesStudies in History and Philosophy of Science Part B: Studies in History and Philosophy of Modern Physics, 2002
The cosmological constant problem arises at the intersection between general relativity and quantum field theory, and is regarded as a fundamental problem in modern physics. In this paper we describe the historical and conceptual origin of the cosmological constant problem which is intimately connected to the vacuum concept in quantum field theory.

Spatial Statistics for Screening Molecular Structures

open access: yesSmall, EarlyView.
Deep architectures for materials discovery demand vast training data and obscure the structure‐property link. This review shows how spatial statistics offer a physically grounded alternative: voxelized fields and two‐point correlations, compressed by principal component analysis, yield convex, interpretable descriptors. Lean surrogates then reach sub‐2%

An étude on global vacuum energy sequester

open access: yesJournal of High Energy Physics, 2017
Recently two of the authors proposed a mechanism of vacuum energy sequester as a means of protecting the observable cosmological constant from quantum radiative corrections.

Calculation of the Cosmological Constant for the Planetary System in Schwarzschild’s Cosmological Model

open access: yesUniverse, 2022
In this work, the static cosmological model of the Schwarzschild solution for the solar system is proposed taking into account the cosmological constant in the equation of the general theory of relativity (GTR) proposed by A. Einstein.

Eternal Higgs inflation and the cosmological constant problem [PDF]

open access: yes, 2015
We investigate the Higgs potential beyond the Planck scale in the superstring theory, under the assumption that the supersymmetry is broken at the string scale.

Relationship: Orientation, politics, ethics, and the idea and practice of self‐determination

open access: yesAustralian Journal of Public Administration, EarlyView.
Abstract First Nations people deeply value relational modes of organising politics, governance, and social order that do not feature in European‐derived political ordering or in dominant governance and policy scholarship. While Indigenous peoples have long sought equitable and respectful relationships in the context of forced colonial engagement, the ...

Brane world solution to the cosmological constant problem

open access: yes, 2001
Previous studies showed that there is a positive cosmological constant in the universe. Compared to the Planck or the electroweak scale, the constant is many orders of magnitude smaller than expected within the context of ordinary gravity and quantum ...
