These (and subsequent) measurements highlight the incompleteness of our understanding of the half-filled Landau level: mean-field treatments of the Dirac (Son) and nonrelativistic (Halperin-Lee-Read) composite fermion theories give identical predictions for the locations of oscillation minima; if the effects of Chern-Simons gauge field fluctuations (ignored in any mean-field treatment) are included, the comparison between theory and experiment improves dramatically. |
