Multi(Scale)Gravity: A Telescope for the Micro-World
Ian I. Kogan
This is a talk presented at XXXVIth Rencontres de Moriond, ElectroWeak Interactions and Unified Theories, March 2001. A short review of modern status of multigravity, i.e. modifica…
H-Branes and Chiral Strings
Ian I. Kogan, Nuno B. B. Reis
We add a simple boundary term to the Polyakov action and construct a new class of D-branes with a single null direction. On the string world-sheet the system is described by a sing…
Multigravity in six dimensions: Generating bounces with flat positive tension branes
Ian I. Kogan, Stavros Mouslopoulos, Antonios Papazoglou +1
We present a generalization of the five dimensional multigravity models to six dimensions. The key characteristic of these constructions is that that we obtain solutions which do n…
Multi-Localization in Multi-Brane Worlds
Ian I. Kogan, Stavros Mouslopoulos, Antonios Papazoglou +1
We study bulk fields in various multi-brane models with localized gravity. In the case of spin 0, 1/2 and 3/2 fields, the non-trivial background geometry itself can induce (multi-)…
Radion in Multibrane World
Ian I. Kogan, Stavros Mouslopoulos, Antonios Papazoglou +1
The radion dynamics related to the presence of moving branes with both positive or negative tensions is studied in the linearized approximation. The radion effective Lagrangian is…
Deconfinement at N>2: SU(N) Georgi-Glashow model in 2+1 dimensions
Ian. I Kogan, Alex Kovner, Bayram Tekin
We analyse the deconfining phase transition in the SU(N) Georgi-Glashow model in 2+1 dimensions. We show that the phase transition is second order for any N, and the universality c…
