Generation of tunable correlated atom beams in an optical lattice
Spontaneous four wave mixing performed in a moving 1D optical lattice.
Spontaneous four wave mixing (SFWM) of matter waves is a source of non-classical atomic pair states, similar to the twin photon states generated through parametric down-conversion and widely used in quantum optics. We perform here SFWM in a moving 1D optical lattice, from a metastable helium BEC. Thus, pairs of atoms are efficiently scattered into two matter beams, whose momenta and population are tunable.
We study the beams' correlation properties, which are crucial for applications in quantum atom optics experiments.
