    The phase of matter waves depends on proper time and is therefore susceptible to special-relativistic (kinematic) and gravitational (redshift) time dilation. Hence, it is conceivable that atom interferometers measure ...
  • Multi-loop atomic Sagnac interferometry 
    Schubert, Christian; Abend, Sven; Gersemann, Matthias; Gebbe, Martina; Schlippert, Dennis; Berg, Peter; Rasel, Ernst M. ([London] : Macmillan Publishers Limited, part of Springer Nature, 2021)
    The sensitivity of light and matter-wave interferometers to rotations is based on the Sagnac effect and increases with the area enclosed by the interferometer. In the case of light, the latter can be enlarged by forming ...
