Bubble Universe from Flat Spaces
Eduardo Guendelman, Jacov Portnoy
We show by matching two flat spaces one in Minkowski coordinates ( empty space) and the other in Minkowski coordinates after a special conformal transformation (also empty space) t…
Brane world creation from flat or almost flat space in dynamical tension string theories
E. I. Guendelman, J. Portnoy
There is great interest in the construction of brane worlds, where matter and gravity are forced to be effective only in a lower dimensional surface , the brane . How these could a…
Is our vacuum stable?
E. I. Guendelman, J. Portnoy
The stability of our vacuum is analyzed and several aspects concerning this question are reviewed. 1) In the standard Glashow-Weinberg-Salam (GWS) model we review the instability t…
The Universe out of an Elementary Particle?
E. I. Guendelman, Jacov Portnoy
We consider a model of an elementary particle as a 2 + 1 dimensional brane evolving in a 3 + 1 dimensional space. Introducing gauge fields that live in the brane as well as normal…
