  • Exact BPS bound for noncommutative baby Skyrmions 
    Domrin, Andrei V.; Lechtenfeld, Olaf; Linares, Román; Maceda, Marco (Amsterdam : Elsevier B.V., 2013)
    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 solitonic solutions have been identified analytically ...
  • Noncommutative deformation of the Ward metric 
    Goffeng, Magnus; Lechtenfeld, Olaf (Trieste : International School for Advanced Studies, 2011)
    The moduli-space metric in the static non-Abelian charge-two sector of the Moyal-deformed CP1 sigma model in 1+2 dimensions is analyzed. After recalling the commutative results of Ward and Ruback and the ?-regularized ...
