Momentum gauge fields from curved momentum space through Kaluza-Klein reduction
Eduardo Guendelman, Fabian Wagner
In this work we investigate the relation between curved momentum space and momentum-dependent gauge fields. While the former is a classic idea that has been shown to be tied to min…
Momentum Gauge Fields and Non-Commutative Space-Time
E. Guendelman, D. Singleton
In this work we present a gauge principle that starts with the momentum space representation of the position operator () rather…
Relieving String Tension By Making Baby Universes in a Dynamical String Tension Braneworld Model
Eduardo I. Guendelman, Zeeya Merali
String tension fundamentally determines the properties of strings; yet its value is often assigned arbitrarily, creating a fine-tuning problem. We describe a mechanism for dynamica…
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…
Unifying Inflation with early and late Dark Energy in Multi-Fields: Spontaneously broken scale invariant TMT
Eduardo Guendelman, Ramon Herrera, David Benisty
A unified multi scalar field model with three flat regions is discussed. The three flat regions are the inflation, early and late dark energy epochs. The potential is obtained by a…
