Specular mirrors in atom interferometers Effects based on quantum clock interference rely on atom interferometers with a non-vanishing proper time difference. We propose an atom interferometer consisting of two beam splitters to separate and recombine the two branches of the interferometer, and two specular mirrors in the middle that invert the incoming momentum. We show… View Article

The twin paradox in light pulse atom interferometers Proper time determines the phase of matter waves, such that atom interferometers are in principle susceptible to time dilation. However, the kinetic symmetry of the interferometer determines whether proper time differences have an impact on the measured interference pattern. We show which type of light-pulse atom interferometers,… View Article
