Phys. Rev. B 40, 1973–1975 (1989)Clusters in a two-dimensional electron gas at even-denominator filling factorsReceived 23 January 1989; published in the issue dated 15 July 1989 Stability of the homogeneous two-dimensional electron gas in strong magnetic fields at even-denominator fractional occupations is studied. An analytical method for calculation of energy gaps in clusters with an arbitrary number of particles is developed, and it is shown that small clusters (quantum lakes) have size-dependent energy gaps at any simple fractional filling factors. © 1989 The American Physical Society URL:
