BOSONIZATION OF ONE-DIMENSIONAL EXCLUSIONS AND CHARACTERIZATION OF LUTTINGER LIQUIDS

We achieve a bosonization of one-dimensional ideal gas of particles obeying exclusion statistics lambda (so called lambda exclusons) at low temperatures, resulting in a new variant of c = 1 conformal field theory with compactified radius R = root 1/lambda. These ideal excluson gases exactly reproduce the low-T critical properties of Luttinger liquids, so they can be used to characterize the fixed points of the latter. Generalized ideal gases with mutual statistics and nonideal gases with Luttinger-type interactions have also similar low-T behavior, controlled by an effective statistics varying in a fixed-point line.
