Trapped ultracold fermions in double-wells

Trapped ultracold fermions in double-wells

The top row illustrates a ground state boson-like (paired, i.e. bunched) configuration of two ultracold atoms trapped in a double-well potential on the left, and on the right, a fermion-like (unpaired, or anti-bunched) configuration of the two atoms. The atoms are represented by balls with the atoms’ spins indicated by the up and down arrows. The wave functions corresponding to the atoms are superimposed on the atoms.

In the bottom row, we show the theoretically predicted two-atom momentum (denoted as k1 and k2) correlation maps corresponding to the configurations in the top row. These momentum correlation maps, which contrast in the two cases shown here, could be measured in laboratory experiments when the double-well trapping potentials are turned off, and the results can be used to fully characterize the flights taken by the two atoms for each of the starting configurations. Such information, uncovered by the theoretical calculational modeling of Georgia Tech physicists, are targeted at aiding the design and analysis of ultracold atom experiments aiming at revealing the quantum nature of ultracold matter.
