Abstract
The region of filling factors 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 and , while the states at and remain compressible. Our observations at and are first steps towards understanding emergent topological order in these fractional quantum Hall states.
