Abstract
As discovered in the quantum Hall effect, a very effective way for\nstrongly-repulsive electrons to minimize their potential energy is to aquire\nnon-zero relative angular momentum. We pursue this mechanism for interacting\ntwo-dimensional electrons in zero magnetic field, by employing a representation\nof the electrons as composite bosons interacting with a Chern-Simons gauge\nfield. This enables us to construct a dual description in which the fundamental\nconstituents are vortices in the auxiliary boson fields. The resulting\nformalism embraces a cornucopia of possible phases. Remarkably,\nsuperconductivity is a generic feature, while the Fermi liquid is not --\nprompting us to conjecture that such a state may not be possible when the\ninteractions are sufficiently strong. Many aspects of our earlier discussions\nof the nodal liquid and spin-charge separation find surprising incarnations in\nthis new framework.\n
