... probe these atomic gases. In the first case, we use an auto-correlation technique to study the interference pattern produced by a gas of atoms, slightly above the Bose-Einstein condensate transition temperature. A moving optical lattice is used to split and recombine the single particle atomic wavef ...

It then follows that if the exact field pattern emitted by the body is precisely returned to the body, exactly opposite polarizations are produce ...

For a diffraction pattern to appear on the screen, a convex lens is placed between the slit and screen to provide convergence of the light rays. 14.5 Single-Slit Diffraction In our consideration of Young ...

This is equivalent to 570 as rms phase jitter from 1 Hz to 1 MHz. To our knowledge this is the lowest reported phase jitter bet ...
