Description
We consider the classical integrable structure of two-dimensional non-linear sigma models defined on 3D Schrodinger spacetime (called the Schrodinger sigma models). The global symmetry is SL(2)_L x U(1)_R. The SL(2)_L symmetry is enhanced to the Yangian Y(sl(2)). We show that the U(1)_R symmetry is enhanced to a Jordanian twisted Yangian. Finally I will discuss the Landau-Lifshitz limit if I have time.
