Scattering of Noncommutative Waves and Solitons in a Supersymmetric Chiral Model in 2+1 Dimensions
Christian Gutschwager, Tatiana A. Ivanova, Olaf Lechtenfeld
Interactions of noncommutative waves and solitons in 2+1 dimensions can be analyzed exactly for a supersymmetric and integrable U(n) chiral model extending the Ward model. Using th…
Superfield Formulation of Nonlinear N=4 Supermultiplets
S. Bellucci, S. Krivonos, O. Lechtenfeld +1
We propose a unified superfield formulation of N=4 off-shell supermultiplets in one spacetime dimension using the standard N=4 superspace. The main idea of our approach is a "gluin…
Noncommutative Solitons
Olaf Lechtenfeld
Solitonic objects play a central role in gauge and string theory (as, e.g., monopoles, black holes, D-branes, etc.). Certain string backgrounds produce a noncommutative deformation…
N=2 supersymmetric unconstrained matrix GNLS hierarchies are consistent
F. Delduc, O. Lechtenfeld, A. S. Sorin
We develop a pseudo-differential approach to the N=2 supersymmetric unconstrained matrix (k|n,m)-Generalized Nonlinear Schroedinger hierarchies and prove consistency of the corresp…
N=4 superconformal Calogero models
Anton Galajinsky, Olaf Lechtenfeld, Kirill Polovnikov
We continue the research initiated in hep-th/0607215 and apply our method of conformal automorphisms to generate various N=4 superconformal quantum many-body systems on the real li…
Supersymmetric noncommutative solitons
Olaf Lechtenfeld
I consider a supersymmetric Bogomolny-type model in 2+1 dimensions originating from topological string theory. By a gauge fixing this model is reduced to a supersymmetric U(n) chir…
