Our research interests are centered on the development of quantum sensors of rotation and acceleration based on cold atoms (quantum metrology), the application of these sensors to the tests of General Relativity, the investigation of many-body quantum effects in Bose-condensed vapors (including quantum simulation), and the investigation of ultra-fast laser-induced phenomena.
