Abstract:
Atom interferometers have been part of the metrology and quantum sensing toolbox for more than a decade. By taking advantage of the several degrees of freedom and the coherent properties of ultra-cold atom systems and Bose Einstein Condensates (BEC), time, gravity or rotation measurements can reach unprecedented precision. Current projects aim at competing with LIGO in the arena of gravitational waves detection and they are the motor of a technological arms-race at ultra-low temperatures. In addition, there exists a drive towards miniaturization and compactness: the interrogation time of typical free-fall interferometers is usually limited by, precisely, the atom’s free fall time. At this crossroads surges the idea of guided atom interferometry, where the atomic clouds are trapped in matter waveguides and interrogation times can be made arbitrarily long. This concept led me to I Lesanovsky and W. von Klitzing’s idea of time averaged adiabatic ring potentials to trap and manipulate BECs without destroying their coherent properties. I joined Dr. von Klitzing’s group after my BSc at the University of Valencia and I will present our recent experiments on BEC accelerators and atom-clock guided interferometry.
