Abstract

The thematic project involves a viability study of quantum sensors based on the interaction between cold atoms and plasmons or evanescent waves near nanostructured surfaces or metamaterials. In this post-doctoral project we will study the coupling of atoms to light modes formed near nanofiber tips pumped by lasers. The postdoctoral fellow will construct a standard magneto-optical trap experiment into which he will insert a nanofiber provided by a collaborating laboratory in Germany. He will study three situations: 1. the impact of the light field formed at the tip of a laser-pumped nanofiber on the atomic motion (repulsion or confinement); 2. collection of light emitted by excited atoms into the fiber; 3. transport of light through atomic clouds (injection and light collection) at different locations.
