Projection on higher Landau levels and non-commutative geometry

arXiv:hep-th/0112181 · doi:10.1088/0305-4470/35/20/307

Abstract

The projection of a two dimensional planar system on the higher Landau levels of an external magnetic field is formulated in the language of the non commutative plane and leads to a new class of star products.
