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

Abstract : In September 2015, the LIGO detector realized the first direct observation of gravitational waves. This ground-based detector, as well as the European detector VIRGO, is based on purely optical technologies. These instruments are extremely sensitive around 100 Hz b
