Free lunch served at 12:00 pm.

I will discuss the quantum dissipation of a bright soliton in a quasi-one-dimensional bosonic superfluid. I will argue that due to the integrability of the original problem, usual Ohmic friction proportional to a velocity is absent. It uncovers the non-Ohmic and non-Markovian friction, which can be interpreted as the backreaction of Bogoliubov quasiparticles inelastically scattered by an accelerating soliton, which represents an analogue of the Abraham-Lorentz force known in electrodynamic.

The talk is based on the recent work by Dmitry K. Efimkin, Johannes Hofmann and Victor Galitski -http://arxiv.org/abs/1512.07640
