Abstract

We systematically discuss properties of quantum disordered states of the quantum Hall bilayer at \ensuremathν_T=1. For one of them, the so-called vortex metal state, we find off-diagonal long-range order of algebraic kind, and derive its transport properties. It is shown that this state is relevant for the explanation of the ``imperfect'' superfluid behavior and persistent intercorrelations, for large distances between layers, that were found in experiments.
