Offer Description
The applicant (M/F) will participate to the development of the heart of the transportable Ytterbium lattice clock at SYRTE, Observatoire de Paris. The clock will be attached to the large scale infrastructure REFIMEVE+ (optical fiber network disseminating an ultrastable reference at 1542 nm), in order to enable remote frequency comparisons with the ~12 stationary European optical clocks. Given the sensitivity of atomic clocks to the local gravitational potential, these measurements will notably result in a cartography of the Earth potential with an unprecedented resolution.
The applicant (M/F) will be in charge of exploiting the existing ultra-high vacuum Physics package to optimize a combination of optical molasses (399 nm), 2D/3D magneto-optical traps (399 nm/556 nm), and optical lattices (759 nm) to capture neutral ytterbium at high rates. This trapping in a so-called ‘magic’ lattice will be designed to reach the Lamb-Dicke regime. He/she will design a time sequence allowing the capture of >1e4 atoms in less than 100 ms, while reaching temperatures close to 1 µK in the longitudinal direction. Finally he/she will supervise the programming aspects in order to manage this sequence with reliability and agility.
The Ytterbium teams is composed of 6 people, and the post-doctoral researcher must have good skills in supervising as he/she will notably assist the management of the PhD thesis projects.
The new atomic clock will benefit from the expertise accumulated at SYRTE during the development of the three stationary optical clocks (based on strontium and mercury). A good team spirit, and an advanced level in English are therefore absolutely mandatory.
The project is funded by ANR (Agence Nationale pour la Recherche) and CNES (Centre national d’études spatiales). The initial contract is 12 months and can be extended.
