Towards a Gyroscope with a Large Interferometer Area, Testing the Fundamentals of Physics

After having investigate the limits of our previous inertial sensor using a cold atom interferometer of caesuim in the all six axis of inertia [1], we project to built a brand new second and better version of interferometer, in order to improve the high accuracy and to be able to do some testing of fundamental physics (atomic neutrality, Aharonov-Bohm effect, electric polarisability) [2]. The new gyroscope will stand at 1 meter high, with a large sensing area and interrogation time. We expect also to use large momentum transfer beam splitter [3]. More details of the experiment under construction will be given.\\[3pt] References:\\[0pt] [1] Six axis Inertial Sensor Using Cold Atom Interferometry, B. Canuel and al, Phys. Rev.
