The purpose of the workshop is to create an interdisciplinary platform for the discussion of the phenomenon of quantum reflection.

Quantum reflection is a classically counterintuitive phenomenon whereby the motion of particles is reverted "against the force" acting on them. This effect manifests the wave nature of particles and influences collisions of ultracold atoms and interaction of atoms with solid surfaces.

Quantum reflection of cold atoms from surfaces occurs on the attractive tails of long-range atom surface potentials, and takes place at mesoscopic distances on the order of a fraction of a micron. Because of that, studies of quantum reflection are closely related to studies of the long-range atom-surface interactions and contribute to our understanding of the interface between quantum world and the macroscopic world in general.

Observation of quantum reflection has become possible thanks to recent advances in trapping and cooling atoms. Utilization of this effect has only begun and holds many exciting promises. The goal of the workshop is to present the recent results and applications of quantum reflection in the areas of atomic, molecular, optical and surface physics, and to discuss its potential for science and technology, notably for the understanding of quantum mechanics, for realization of experiments testing quantum electrodynamics and gravity, and for applications in the fields of quantum optics and nanotechnology.
