Observation of Roton Mode Population in a Dipolar Quantum Gas
The concept of a roton, a special kind of elementary excitation, forming a minimum of energy at finite momentum, has been essential to understand the properties of superfluid (4)He 1. In quantum liquids, rotons arise from the strong interparticle interactions, whose microscopic description remains d...
