Topological Phase Transition in the $\nu =2/3$ Quantum Hall Effect

Abstract

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