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.

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…

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.…

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.…

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…

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…
