Query: Quantum Dynamics of Pseudospin Solitons in Double-Layer Quantum Hall
  Systems   Pseudospin solitons in double-layer quantum Hall systems can be introduced by
a magnetic field component coplanar with the electrons and can be pinned by
applying voltages to external gates. We estimate the temperature below which
depinning occurs predominantly via tunneling and calculate low-temperature
depinning rates for realistic geometries. We discuss the local changes in
charge and current densities and in spectral functions that can be used to
detect solitons and observe their temporal evolution.
