Job description

Exail quantum sensors (EQS) in collaboration with LP2N is looking for applicants for a PhD position within the MARIE SKŁODOWSKA-CURIE Doctoral network MAWI.World leader in the production of industrial-grade quantum gravimeters, EQS provides turnkey absolute gravimeters based on matter-wave interferometry for geophysicists and geodesists.The LP2N is deeply involved in the construction of the MIGA large-scale gravity antenna [1], a research infrastructure based on matter wave interferometry in development at the LSBB underground laboratory. MIGA will provide precise measurements of the local gravity sensed by a network of three free-falling atom test masses distant up to 150 m.In the first part of the thesis, the applicant will be working on the most advanced instrument developed at EQS, the Differential Quantum Gravimeter (DQG) [2], a double matter-wave interferometer able to measure simultaneously the local gravity acceleration and its gravity gradient [3]. The work will concentrate on optimizing the performances of the device and its accuracy above the current state of the art and using it to perform useful measurements for geophysics or civil engineering.In a second part the student will be involved within the LP2N in the MIGA project, where his/her work will be focused on the development of advanced atom gradiometry techniques. In particular, he/she will develop new metrological models and simulations for high-sensitive measurement of the gravity gradient over the horizontal direction. A simultaneous operation with the DQG will be explored to open multi-axial sensing of the gravitational field.Work will involve experimental work, data analysis, theory and eventually field measurements with the DQG. Within MAWI, the applicant will be able to visit other laboratories of the network as well as workshops and summer schools.
