【 摘 要 】

We discuss the composite fermion pairing state in bilayer quantum Hall systems. After evaluation of the range of the interlayer separation in which the quantum Hall state is stabilized, we discuss the effect of interlayer tunneling on the composite fermion pairing state at nu=1/2. We show that there is a cusp at the transition point between the Halperin (3,3,1) state and the Pfaffian state.
