Contribution

It introduces a dressed anyon model incorporating screening effects and compares it with the traditional Chern-Simons construction.

Findings

Dressed anyons exhibit a screening factor in their spin.

Structural similarity with Chern-Simons theory aids in calculations.

Comparison shows differences and similarities with conventional models.

Abstract

Anyon gas with interparticle (retarded) Coulomb interaction has been studied. The resulting system is shown to be a collection of dressed anyons, with a screening factor introduced in their spin. Close structural similarity with the Chern-Simons construction of anyons has helped considerably in computing the screening effect. Finally the present model is compared with the conventional Chern-Simons construction.
