Offer Description

The PhD project is part of the FETOPEN project CRYST3 funded by the European Research Council. This research program requires (i) micro-confining and laser cooling rubidium atom inside the core of a hollow core fiber, (ii) exploring cooperative effects and (iii) generation and characterization of superradiance. Also, the project comprises theoretical and simulations work, that will be undertaken by this PhD. The PhD program entails two objectives. The first one consists in studying the effects induced by the surface roughness of the core contour of hollow fibers on guided light scattering and on the evolution of the modal content during propagation. This modal dynamics will be essential in the study of the spectroscopic dynamics of micro-confined atoms in the fiber core. For this, 2D+1 simulation tools will be developed, for the first time for hollow core optical fibres, in order to take into account the impact of surface roughness on the dynamics of optical propagation. The simulation will include Bloch's equations solving to study the optomechanical dynamics of atoms in the fiber. The result would lead to a unique numerical platform to simulate both the spatial modes of the atoms filled fiber, their propagative dynamics as well as the spectroscopic dynamic of the in-fiber atoms. The second objective will focus on the design of new fiber structures able to preferentially guide modes with specific spatial structures and able to modify their opto-mechanical impact  on atoms, and therefore to carry out "intra-fiber" atom optics experiments such as trapping and cooling of atoms or the atom-surface interaction investigation. These will be the necessary milestones for the development of a cold atom PMC.

The PhD program will be undertaken in collaboration with the University of Modena in Italy.

The PhD work will be undertaken at the Gas-Phase Photonic and Microwave Materials group (GPPMM) at Xlim CNRS research Institute, University of Limoges, France. The

GPPMM is world-renowned research group for its mix of experimental and theoretical investigations into new hollow-core photonic crystal fibres (HC-PCF) and their applications in nonlinear and quantum optics applications. The group works in an inventive and highly interactive environment, with internal interactions being complemented by active international collaborations. Limoges is a pleasant and attractive city in the west-central France, close to Bordeaux and just 2ó hours by train from Paris.
