Query: Charged Pseudospin Textures in Double-Layer Quantum Hall Systems with
  Spontaneous Interlayer Coherence   We report on a Hartree-Fock approximation study of the meron
pseudospin-texture excitations of the broken-symmetry incompressible ground
states of double-layer quantum Hall states at $\nu =1$. We have obtained
results for meron core energies and core sizes. We use these to estimate the
charge gap which determines the activation energy for dissipation in the
quantum Hall effect.
