Abstract
The odd structure of the fractional filling hierarchy, which is
referred to as the fractional quantum Hall effect, is studied in higher
Landau levels using the commensurability condition. The hierarchy of fillings
that are derived in this manner is consistent with the experimental
observations in the first three Landau levels. The relative poverty of the
fractional structure in higher Landau levels compared with the lowest Landau
level is explained using commensurability topological arguments. The
commensurability criterion for correlated states specific for higher Landau
levels (with ), including also the paired states at half fillings of
the spin-subbands of these levels, is formulated.
