✦ Synopsis

Quantum coherence develops spontaneously in bilayer quantum Hall systems when the Coulomb exchange energy is dominant. We argue that there exists a distinctive transition between the coherent phase and the resonant phase because di erent types of skyrmions are excited in these two phases.
