Gauge Equivalence, Supersymmetry and Classical Solutions of the ospu($1,1/1$) Heisenberg Model and the Nonlinear Schrödinger Equation

V. G. Makhankov, R. Myrzakulov, O. K. Pashaev

An integrable generalization of the continuous classical O$(2,1)$ pseudospin Heisenberg model to the case of the ospu$(1,1/1)$ superalgebra is constructed. The gauge equivalence of…
