The University Sorbonne Paris Nord is opening a Research Associate position in experimental molecular and quantum physics. Ideally, the starting date should be between October and December 2022. The length of the contact will be 15 months.
The position is funded by the Labex FIRST-TF project ‘Probing molecular gases under confinement', which is a collaborative project between an experimental group of the University Sorbonne Paris Nord and the group of Fetah Benabid in XLim, Limoges.
The Sorbonne Paris Nord group (SAI: Spectroscopie Atomique aux Interfaces) consists of 4 permanent members of staff and 3 PhD students. The group is part of the Laboratoire de Physique des Lasers, located at the northern suburbs of Paris (about 10min from central Paris by public transport). Further details can be found HERE.
For the current project, the SAI group collaborates with the MMTF (Métrologie Molécules et Tests Fondamentaux) group (details HERE). The research topic involves the experimental study of molecular gases confined within thin cells of micrometric thickness comparable to the excitation wavelength.
1) The first goal of the project is to develop compact frequency references based on thin cell transmission spectroscopy of acetylene and if possible compare the performance of such devices against a metrological reference. An alternative technology for fabricating compact molecular frequency references, by using a hollow core fiber filled with acetylene, will also be tested in collaboration with the group of Fetah Benabid.
2) The second goal of the project will be to probe molecules under extreme confinement (cells nanometric thickness) in order to probe the fundamental molecule surface (Casimir-Polder) interaction.
The successful applicant will have a good PhD degree in experimental physics and a solid background in molecular or atomic physics, quantum physics and optics. Experience with fabrication methods is not a requirement but could be a bonus. Willingness to interface with theoretical physicists and other experimentalists is also required for this position. The successful applicant can also spend some time (1-2 months) in the group of Fetah Benabid in Limoges to fabricate and characterise acetylene filled hollow core fibers.
