Fermi-sea-like correlations in a partially filled Landau level
arXiv:cond-mat/9704019 · doi:10.1103/PhysRevB.56.12411
Abstract
The pair distribution function and the static structure factor are computed for composite fermions. Clear and robust evidence for a $2k_F$ structure is seen in a range of filling factors in the vicinity of the half-filled Landau level. Surprisingly, it is found that filled Landau levels of composite fermions, i.e. incompressible FQHE states, bear a stronger resemblance to a Fermi sea than do filled Landau levels of electrons.
