GAUGE INVARIANCE IN NON-RELATIVISTIC MANY-BODY THEORY
Jürg Martin Fröhlich, Urban M. Studer
We review some recent results on the physics of two-dimensional, incompressible electron and spin liquids. These results follow from Ward identities reflecting the U(1) em × SU(2) spin -gauge invariance of non-relativistic quantum mechanics. They describe a variety of generalized quantized Hall effects.
