Abstract
We show that within the Hartree-Fock approximation, self-consistent solutions exist for the two-dimensional electron gas in the extreme quantum limit which show energy cusps at filling factors of odd denominator only. The associated gaps are larger for rational factors represented by simple fractions. One such state holding 0.5 electrons in the charge-density-wave unit cell is discussed in detail.Keywords
