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.

Recent experimental work on the quantized Hall state at total filling factor n T ΒΌ 1 in bilayer 2D electron systems has revealed a number of striking phenomena, including a giant and sharply resonant enhancement of the interlayer tunneling conductance at zero bias. The tunneling enhancement is a com
