Wilson RG of Noncommutative
Badis Ydri, Rachid Ahmim, Adel Bouchareb
We present a study of phi-four theory on noncommutative spaces using a combination of the Wilson renormalization group recursion formula and the solution to the zero dimensional ve…
Bertotti-Robinson and soliton string solutions of minimal supergravity
Adel Bouchareb, Chiang-Mei Chen, Gérard Clément +1
We report on a series of new solutions to five-dimensional minimal supergravity. Our method applies to space-times with two commuting Killing symmetries and consists in combining d…
Bertotti-Robinson solutions of D=5 Einstein-Maxwell-Chern-Simons-Lambda theory
Adel Bouchareb, Chiang-Mei Chen, Gérard Clément +1
We present a series of new solutions in five-dimensional Einstein-Maxwell-Chern-Simons theory with an arbitrary Chern-Simons coupling and a cosmological constant . For gener…
On the Problem of Vacuum Energy in FLRW Universes and Dark Energy
Badis Ydri, Adel Bouchareb
We present a (hopefully) novel calculation of the vacuum energy in expanding FLRW spacetimes based on the renormalization of quantum field theory in non-zero backgrounds. We comput…
The fate of the Wilson-Fisher fixed point in non-commutative ϕ^4
Badis Ydri, Adel Bouchareb
In this article we study non-commutative vector sigma model with the most general ϕ^4 interaction on Moyal-Weyl spaces. We compute the 2- and 4-point functions to all orders in the…
generating technique for minimal D=5 supergravity and black rings
Adel Bouchareb, Chiang-Mei Chen, Gerard Clement +3
A solution generating technique is developed for D=5 minimal supergravity with two commuting Killing vectors based on the U-duality arising in the reduction of the theory to…
