Abstract: (Elsevier)
Certain (4,4)-supersymmetric (1+1)-dimensional sigma-models admit a scalar potential. We exhibit models of this type for which there are static particle-like solutions stabilized by a three-vector topological charge Q . These solutions form a special class of (generally time-dependent) “ Q -kink” solutions stabilized by a quaternionic charge Q=(Q 0 , Q ) , where Q 0 is a Noether charge. Q -kinks saturate a Bogomol'nyi-type bound and break half the supersymmetry. As solutions of a four-dimensional field theory they constitute examples of type II supermembranes.- sigma model: nonlinear
