Color Superfluidity and “Baryon” Formation in Ultracold Fermions
Color Superfluidity and “Baryon” Formation in Ultracold Fermions
We study fermionic atoms of three different internal quantum states (colors) in an optical lattice, which are interacting through attractive on site interactions, U<0. Using a variational calculation for equal color densities and small couplings, |U|<|UC|, a color superfluid state emerges with a tendency to domain formation. For |U|>|UC|, triplets …
