In particular, the dispersion of the composite fermion exciton, which is the lowest energy spin conserving neutral excitation, displays filling-factor-specific minima called \"magnetoroton\" minima. Simon and Halperin employed the Chern-Simons field theory of composite fermions [Phys. Rev. B {\\bf 48}, 17368 (1993)] to predict the magnetoroton minima positions.
