摘要：

We discuss the large-scale physics of incompressible Hall fluids from the point of view of universality and symmetry. We show that, in the scaling limit, incompressible Hall fluids are described by certain topological Chern-Simons gauge theories. The gauge field strengths are dual to conserved currents of the fluid. The Chern-Simons gauge theories unambiguously predict current algebras of chiral edge currents. We describe incompressible Hall fluids exhibiting edge currents which form a non-abelian Kac-Moody current algebra at level 1. Some new incompressible Hall fluids are described. Our analysis is derived from very general physical principles and should therefore lead to reliable results.
