Аннотация:he two-dimensional purely magnetic Schrödinger operator for the nonrelativistic particle with a spin of 1/2 in a magnetic field has some remarkable properties, that were discovered in the late 70s: its strongly degenerate in the ground state and it admits supersymmetry. In the present work we investigate the special case where the magnetic flux of the periodic field through the elementary cell equals zero. This case has not been covered in the previous publications. An interesting connection with the theory of solitons, in particular with Burgers-like systems and their two-dimensional analogues, is revealed. Their linearizability properties are simpler than some famous systems, such as KdV and KP. Members of the Aharonov-Bohm-type system with quantized magnetic flux play a special role in the investigation of this case.
