Multiple-quasiparticle agglomerates at ν=2/5

Abstract

We investigate the dynamics of quasiparticle agglomerates in edge states of the Jain sequence for ν=2/5. Comparison of the Fradkin-Lopez model with the Wen one is presented within a field theoretical construction, focusing on similarities and differences. We demonstrate that both models predict the same universal role for the multiple-quasiparticle agglomerates that dominate on single quasiparticles at low energy. This result is induced by the presence of neutral modes with finite velocity and is essential to explain the anomalous behavior of tunneling conductance and noise through a point contact.
