The edge state network model and the global phase diagram

Kentaro Nomura, Daijiro Yoshioka

Research output: Contribution to journalArticlepeer-review


The effects of randomness are investigated in the fractional quantum Hall systems. Based on the Chern-Simons Ginzburg Landau theory and considering relevant quasi-particle tunneling, the edge state network model for the hierarchical state is introduced and the plateau-plateau transition and the liquid-insulator transition are discussed. This model has duality which corresponds to the relation of the quantum Hall liquid phase and the Hall insulating phase and reveals a mechanism of plateau transition in the weak coupling regime.
