Class review — 3/8
Hey Class,
The pre-flight for Thursday is ready. Remember that you need to tell me something about your final project soon!
Today we talked about some new things:
Dipole traps. A focused laser beam can trap atoms! The trap depth and trapping frequencies are functions of the light intensity and detuning. A far-detuned trap can confine all Zeeman levels in a hyperfine ground state manifold, unlike a magnetic trap. Traps can be red-detuned (focused beam) or blue-detuned (focused beam with a dark spot in the middle).
Optical lattices. One type of optical lattice is formed from a standing wave of light. Lattices can be 1, 2, or 3 dimensional.
Cheers,
Brian
