SUSY QM and solitons from two coupled scalar fields in two dimensions - art. no. 125023

An analysis and application of the supersymmetry (SUSY) in nonrelativistic quantum mechanics involving two-component wave functions for a stability eq uation corresponding to two coupled real scalar fields is considered. A gen eral positive potential for two coupled real scalar fields in 1+1 dimension s with a SUSY form is investigated in which the associated two-component no rmal modes are non-negative, which leads to classically stable soliton solu tions, and an example is explicitly considered.
