Exotic galilean symmetry in the non-commutative plane, and the Hall effect

arXiv:hep-th/0106089 · doi:10.1088/0305-4470/34/47/314

Abstract

Quantum Mechanics in the non-commutative plane is shown to admit the ``exotic'' symmetry of the doubly-centrally-extended Galilei group. When coupled to a planar magnetic field whose strength is the inverse of the non-commutative parameter, the system becomes singular, and ``Faddeev-Jackiw'' reduction yields the ``Chern-Simons'' mechanics of Dunne, Jackiw, and Trugenberger. The reduced system moves according to the Hall law.

Revised version. The formula for the conserved quantities is corrected; some more references added. 11 pages, LaTex, no figures
