Abstract

We consider a non-Abelian candidate state at filling factor ν=3/7\nu=3/7 state belonging to the parton family. We find that, in the second Landau level of GaAs (i.e. at filling factor ν=2+3/7\nu=2+3/7), this state is energetically superior to the standard Jain composite-fermion state and also provides a very good representation of the ground state found in exact diagonalization studies of finite systems. This leads us to predict that \emph{if} a fractional quantum Hall effect is observed at ν=3/7\nu=3/7 in the second Landau level, it is likely to be described by this new non-Abelian state. We enumerate experimentally measurable properties that can verify the topological structure of this state.
