Abstract
The double-layer nu=2/3 fractional quantum Hall system is studied usin g the edge-state formalism and finite-size diagonalization subject to periodic boundary conditions. Transitions between three different grou nd states are observed as the separation as well as the tunneling betw een the two layers is varied. Experimental consequences are discussed.
