ON THE ELECTROMAGNETIC-INTERACTIONS OF ANYONS

Using the appropriate representation of the Poincare group and a defin ition of minimal coupling, we discuss some aspects of the electromagne tic interactions of charged anyons. In a nonrelativistic expansion, we derive a Schrodinger-type equation for the anyon wave function which includes spin-magnetic field and spin-orbit couplings. In particular, the gyromagnetic ratio for charged anyons is shown to be 2; this last result is essentially a reflection of the fact that the spin is parall el to the momentum in (2 + 1) dimensions.
