Symmetries of field theories on the non-commutative plane
P. A. Horvathy, L. Martina, P. C. Stichel
New developments on the symmetries of non-relativistic field theoretical models on the non commutative plane are reviewed. It is shown in particular that Galilean invariance strong…
The Baryonic Branch of Klebanov-Strassler Solution: a Supersymmetric Family of SU(3) Structure Backgrounds
Agostino Butti, Mariana Graña, Ruben Minasian +2
We exhibit a one-parameter family of regular supersymmetric solutions of type IIB theory that interpolates between Klebanov-Strassler (KS) and Maldacena-Nunez (MN). The solution is…
Enlarged Galilean symmetry of anyons and the Hall effect
P. A. Horvathy, L. Martina, P. Stichel
Enlarged planar Galilean symmetry, built of both space-time and field variables and also incorporating the ``exotic'' central extension is introduced. It is used to describe non-re…
Numerical and asymptotic analysis of the 't Hooft-Polyakov magnetic monopole
P. Forgács, N. Obadia, S. Reuillon
A high precision numerical analysis of the static, spherically symmetric SU(2) magnetic monopole equations is carried out. Using multi-shooting and multi-domain spectral methods, t…
Type II Strings and Generalized Calabi-Yau Manifolds
Mariana Graña, Ruben Minasian, Michela Petrini +1
This is a short version of hep-th/0406137. We show that the supersymmetry transformations for type II string theories on six-manifolds can be written as differential conditions on…
Non-commuting coordinates, exotic particles, & anomalous anyons in the Hall effect
C. Duval, P. A. Horvathy
Our previous ``exotic'' particle, together with the more recent anomalous anyon model (which has arbitrary gyromagnetic factor ) are reviewed. The non-relativistic limit of the…
