Hybridization between iXblue FOG and a 3D quantum accelerometer
For mobile operation of the hybrid accelerometer, it is crucial to compensate for rotations of the sensor head which easily prevent any measurement to be performed. Indeed, due to linear free-fall trajectory of the atomic clouds, a rotation of the reference frame would cause a bad overlapping of the wavepackets in the interferometer. For this purpose, we installed low-noise, high dynamic range and sensitivity Fiber-Optics Gyroscopes (FOGs) along with high bandwidth, pre
Baptiste BATTELIER HDR defense
Baptiste defended his "habilitation a diriger des recherches" on Friday, February 19th 2021. Unfortunately it was fully virtual, but a remake in real life will be planned as soon as possible! Title: LIGHT MANIPULATION OF ULTRA-COLD MATTER WAVES ON BOARD A VEHICLE : FROM FUNDAMENTAL PHYSICS TO INERTIAL NAVIGATION Abstract: Light Manipulation of matter is at heart of atom physics and atom interferometry and the evolution in this field is strongly related to the technology devel
Postdoctoral position: Multi-axis atom interferometry for inertial navigation
We offer a two-year Postdoctoral Research Associate position in the Cold Atoms in Bordeaux group at LP2N. The postdoc position is part of a collaboration between the research laboratories LCAR, LAAS and LP2N and technology company iXblue to advance quantum technology towards the first multi-axis interferometer with ultra-cold atoms using a hybrid atom chip. Most atomic sensor measurements are one-dimensional, meaning they can measure only a single axis of rotation or accelera
Post doc: Ultra-cold atoms in microgravity
The research work of our team focuses on the production of ultra-cold gases in microgravity, covering a large panel of unexplored atomic physics. The postdoc will be strongly involved in the leading of this research activities and the exploration of future experiments. In the context of space applications, the first objective is to achieve atom interferometry with interrogation time of several seconds and more specifically demonstrate performances allowing to test the weak eq
Ph D: Ultra-cold matter waves in microgravity for atom interferometry
Our research group is devoted to the production of ultra-cold quantum gases in microgravity. The main goal is to achieve atom interferometers with large scale factor to push the sensitivity until the fundamental limits of these systems. To test the equivalence principle with quantum particles the ICE project aims to develop a matter wave interferometer with two atomic species operating in microgravity. This apparatus is based on classical atom optics elements, i.e. laser beam
