Abstract

Considered is a quantum system of $N(\ge2)$ charged particles moving in the plane $\Ma{R}^2$ under the influence of a perpendicular magnetic field. Each particle feels the magnetic field concenrated on the positions of the other particles. The gauge potential which gives this magnetic field is called a winding gauge potential. Properties of the Dirac-Weyl operators with a winding gauge potential are investigated. Notions of local quantization and partial quantization are introduced to determine them. Especially, it is proven that existence of the zero-energy states of the Dirac-Weyl operators with a winding gauge potential is well determined by the local quantization and the partial quantization.
