Microgravity at "home"!

Our ZERO-G simulator allows us to launch our 200 kg Cold atom sensor in our lab and gives us access to 500 ms of microgravity every 12 s, in a highly repeatable way. It consists in reproducing a perfect parabola trajectory by controlling and servo locking the position of the experiment thanks to laser rulers and vibrations-free displacement systems. We expect to increase the interrogation time and the sensitivity of our instrument and consequently reach a level of 10-11 for t

Metrology with Potassium is possible!

We present an all-optical technique to prepare a sample of 39K in a magnetically insensitive state with 95% purity while maintaining a temperature of 6 μK. This versatile preparation scheme is particularly well suited to performing matter-wave interferometry with species exhibiting closely separated hyperfine levels, such as the isotopes of lithium and potassium, and opens new possibilities for metrology with these atoms. We demonstrate the feasibility of such measurements by

Title: A cavity enhanced atom interferometer for the MIGA project. Abstract: After 20 years of development, atom interferometry has become an extremely performing probe of accelerations and rotations. Such techniques are now envisioned for future gravitational waves detectors to push further the limitations of state of the art of optical detectors. In this frame, the MIGA (Matter-wave laser Interferometer Gravitation Antenna) instrument will couple atom and optical interferom
