Abstract

The region of filling factors 1/3<ν<2/5 is predicted to support new types of fractional quantum Hall states with topological order different from that of the Laughlin-Jain or the Moore-Read states. Incompressibility is a necessary condition for the formation of such novel topological states. We find that at 6.9 mK incompressibility develops only at ν=4/11 and 5/13, while the states at ν=6/17 and 3/8 remain compressible. Our observations at ν=4/11 and 5/13 are first steps towards understanding emergent topological order in these fractional quantum Hall states.
