Damping of elementary excitations in one-dimensional dipolar Bose gases
In the presence of dipolar interactions, the excitation spectrum of a Bose gas can acquire a local minimum. The corresponding quasiparticles are known as rotons. They are gapped and do not decay at zero temperature. Here we study the decay of rotons in one-dimensional Bose gases at low temperatures....
