Exact BPS bound for noncommutative baby Skyrmions
Andrei Domrin, Olaf Lechtenfeld, Roman Linares +1
The noncommutative baby Skyrme model is a Moyal deformation of the two-dimensional sigma model plus a Skyrme term, with a group-valued or Grassmannian target. Exact abelian soliton…

Sigma-Model Solitons in the Noncommutative Plane: Construction and Stability Analysis
Andrei V. Domrin, Olaf Lechtenfeld, Stefan Petersen
Noncommutative multi-solitons are investigated in Euclidean two-dimensional U(n) and Grassmannian sigma models, using the auxiliary Fock-space formalism. Their construction and mod…
