Fermion generations on a co-dimension 2 brane
Merab Gogberashvili, Paul Midodashvili, Douglas Singleton
We examine the behavior of fermions in the presence of a non-singular thick brane having co-dimension 2. It is shown that one can obtain three trapped zero modes which differ from…
Observable Algebra
Merab Gogberashvili
A physical applicability of normed split-algebras, such as hyperbolic numbers, split-quaternions and split-octonions is considered. We argue that the observable geometry can be des…
Preferred Frame in Brane World
Merab Gogberashvili
In the framework of brane models the postulates of special relativity theory is revised. It is assumed that there exists preferred frame and relativity principle is violated on the…
Unification of Gravity and Electro-Magnetism in Six Dimensions
Merab Gogberashvili
Recently by us was proposed the model where Einstein's equation on the brane was connected with Maxwell's multi-dimensional equations in pseudo-Euclidean space. Based on this idea…
High-dimensional sources for the four-dimensional gravity
M. Chaichian, M. Gogberashvili, A. B. Kobakhidze
We argue that a certain distribution of matter in higher dimensions can provide the correct behaviour of gravity in four dimensions. Some explicit examples illustrating the idea ar…
