Abstract

This paper reports results of our comprehensive theoretical study of the rotons of composite fermions. The calculated roton energies at Landau-level fillings of 1/3, 2/5, and 3/7 are in excellent agreement with the energies measured in inelastic light scattering and ballistic phonon absorption experiments.
