How are light pulses used in atom interferometry?
The energy and couplings along the atoms' path and their interaction the light pulses serve to determine the phase shift between matter waves at the output of the interferometer. Any effect that modifies the potential energy, internal energy, or kinetic energy across the two arms of the interferometer appears in the interferometer phase.
How is the phase of a laser used in interferometry?
For example, in a Mach-Zehnder interferometer we are only sensitive to the phase of the laser at the time that photons are transferred, and all other phase terms cancel out. We therefore use the laser like a ruler to measure exactly how fast the atoms accelerate.
How are atoms steered in an interferometry experiment?
By manipulating the state of the atoms using one of two types of such light pulses, termed Bragg and Raman transitions (see Figures 2 and 3), we steer the matter waves' paths and recombine the matter waves at the end of the experiment. The atoms' trajectories are shown in Figure 1.
How are atom interferometers used in everyday life?
Atom interferometers are used to measure gravitational acceleration, gravity gradients, accelerations, rotations, fundamental constants such as the gravitational constant and the fine structure constant, and can be used to measure or constrain new physics that couples to matter.
