Anomalous Gap Reversal of the $3 + 1/3$ and $3 + 1/5$ Fractional Quantum Hall States

Ethan Kleinbaum, Ashwani Kumar, L. N. Pfeiffer +2

In this work we report the opening of an energy gap at the filling factor $ν = 3 + 1/3$ , firmly establishing the ground state as a fractional quantum Hall state. This and other odd-den…
