Definitions for "ROTON"
A roton is an elementary excitation, or quasiparticle, in superfluid Helium-4. The dispersion relation of elementary excitations in this superfluid shows a linear increase from the origin, but exhibits first a maximum and then a minimum in energy as the momentum increases. Excitations with momenta in the linear region are called phonons; those with momenta close to the minimum are called rotons.

The Roton is a vehicle that featured in the 1980s toyline Masters of the Universe and the animated television series based on the toyline, He-Man and the Masters of the Universe, produced by Filmation.
