Query: Supersymmetric Q-Lumps in the Grassmannian nonlinear sigma models   We construct the N=2 supersymmetric Grassmannian nonlinear sigma model for
the massless case and extend it to massive N=2 model by adding an appropriate
superpotential. We then study their BPS equations leading to supersymmetric
Q-lumps carrying both topological and Noether charges. These solutions are
shown to be always time dependent even sometimes involving multiple
frequencies. Thus we illustrate explicitly that the time dependence is
consistent with remaining supersymmetries of solitons.
