Atom Interferometer Simulator

Interactive atom interferometer: split a cloud of cold atoms with a pi/2-pi-pi/2 laser pulse sequence, let the two paths diverge and recombine, and read out the interference-fringe phase shift caused by acceleration or rotation — the working principle of precision gravimeters and gyroscopes.

Watch a cloud of cold atoms pass through a π/2–π–π/2 laser pulse sequence: the first pulse splits each atom's matter wave into two paths, the second redirects them so they converge, and the third recombines them at a pair of output ports. The population read out at each port traces an interference fringe that shifts with any acceleration or rotation the atoms experienced along the way — the working principle behind cold-atom gravimeters and gyroscopes. Tune the applied acceleration, rotation rate and pulse separation to see how the fringe phase responds.
