Query: Paired and Stripe States in the Quantum Hall System   We study a paired state at the half-filled Landau level using a mean field
theory on the von Neumann lattice. We obtain a microscopic model which shows a
continuous transition from the compressible stripe state to the paired state.
The energy gap in the paired state is calculated numerically at the half-filled
second Landau level.
