Composite Fermion Hall Conductance at $\nu=1/2$

Condensed Matter 2007-05-23 v1

Abstract

We show that in the limit of vanishing bare electron effective mass, and in the presence of particle-hole symmetric disorder (which can be of vanishing strength), the composite fermion Hall conductance is constrained to be 12e2h-{1\over 2}\frac{e^2}{h}. We discuss the implications of this results for the existence and nature of a composite Fermi liquid in the lowest Landau level.
