15. There is another crossing of the lowest two LLs in 2DHSs, namely a crossing of the two spin levels of the HH-S subband. This crossing, which has been studied previously [F. Fischer, R. Winkler, D. Schuh, M. Bichler, and M. Grayson, Phys. Rev. B 75, 073303 (2007) 10.1103/PhysRevB.75.073303]

26. A (Equation presented) FQHE was also reported very recently in bilayer graphene [D.-K. Ki, V. I. Fal'ko, D. A. Abanin, and A. F. Morpurgo, Nano Lett. 14, 2135 (2014) 10.1021/nl5003922].

28. In the higher ((Equation presented)) LL, there is of course the enigmatic even-denominator FQHE observed at (Equation presented) [R. Willett, J. P. Eisenstein, H. L. Störmer, D. C. Tsui, A. C. Gossard, and J. H. English, Phys. Rev. Lett. 59, 1776 (1987) 10.1103/PhysRevLett.59.1776]
29. whose origin is still unknown, but it is more likely described by a one-component (Pfaffian) wave function rather than (Equation presented) [C. Nayak, S. H. Simon, A. Stern, M. Freedman S. Das Sarma, Rev. Mod. Phys. 80, 1083 (2008) 10.1103/RevModPhys.80.1083].
