Screening in Anyon Gas
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-Sim...
متن کاملAnyon Basis of c = 1 Conformal Field Theory
We study the c = 1 conformal field theory of a free compactified boson with radius r = √ β (β is an integer). The Fock space of this boson is constructed in terms of anyon vertex operators and each state is labeled by an infinite set of pseudo-momenta of filled particles in pseudo-Dirac sea. Wave function of multi anyon state is described by an eigenfunction of the Calogero-Sutherland (CS) mode...
متن کاملFrom Random Matrix Theory to Statistical Mechanics - Anyon Gas
Motivated by numerical experiments and studies of quantum systems which are classically chaotic, we take a Random Matrix description of a Hardsphere gas to Statistical Mechanical description. We apply this to Anyon gas and obtain a formal expression for the momentum distribution. Various limiting situations are discussed and are found in agreement with the well-known results on Hard-sphere gas ...
متن کاملRuppeiner geometry of anyon gas.
We derive the thermodynamic curvature of a two-dimensional ideal anyon gas of particles obeying fractional statistics. The statistical interactions of anyon gas can be attractive or repulsive. For attractive statistical interactions, thermodynamic curvature is positive and for repulsive statistical interactions, it is negative, which indicates a more stable anyon gas. There is a special case be...
متن کاملBosonic Chern–simons Field Theory of Anyon Superconductivity
We study the Quantum Field Theory of nonrelativistic bosons coupled to a Chern–Simons gauge field at nonzero particle density. This field theory is relevant to the study of anyon superconductors in which the anyons are described as bosons with a statistical interaction. We show that it is possible to find a mean field solution to the equations of motion for this system which has some of the fea...
