  author={George Lavrelashvili},
Department of Theoretical Physics, A.Razmadze Mathematical InstituteGE-0193 Tbilisi, Georgia(Dated: February 24, 2010)Instability of 6 dimensional Rubakov-Shaposhnikov model is reinvestigated. It is shown that themodel is unstable in scalar perturbations sector with very particular instability pattern: there areno unstable modes for the first two lowest angular harmonics, m = 0 and m = 1, whereas there is asingle negative mode for each higher m.

On localization of universal scalar fields in a tachyonic de Sitter thick braneworld

Braneworld models may yield interesting effects ranging from high-energy physics to cosmology, or even some low-energy physics. Their mode structure modifies standard results in these physical realms



Phenomenology, astrophysics and cosmology of theories with submillimeter dimensions and TeV scale quantum gravity

We recently proposed a solution to the hierarchy problem not relying on low-energy supersymmetry or technicolor. Instead, the problem is nullified by bringing quantum gravity down to the TeV scale.

An Alternative to compactification

Conventional wisdom states that Newton's force law implies only four noncompact dimensions. We demonstrate that this is not necessarily true in the presence of a nonfactorizable background geometry.

A Large mass hierarchy from a small extra dimension

We propose a new higher-dimensional mechanism for solving the hierarchy problem. The weak scale is generated from the Planck scale through an exponential hierarchy. However, this exponential arises

QUANTUM PHYSICS; PARTICLES AND FIELDS 4553 A nodal theorem for coupled systems of Schrodinger equations and the number of bound states

It is shown that the number of bound states of coupled systems of radial Schrodinger equations can be found by computing the number of zeros of a suitable determinant. This is related to the concept

Observational Evidence from Supernovae for an Accelerating Universe and a Cosmological Constant

We present spectral and photometric observations of 10 Type Ia supernovae (SNe Ia) in the redshift range 0.16 ≤ z ≤ 0.62. The luminosity distances of these objects are determined by methods that

Measurements of Ω and Λ from 42 High-Redshift Supernovae

We report measurements of the mass density, ΩM, and cosmological-constant energy density, ΩΛ, of the universe based on the analysis of 42 type Ia supernovae discovered by the Supernova Cosmology
