We study harmonically trapped, unpolarized fermion systems with attractive
interactions in two spatial dimensions with spin degeneracies Nf = 2 and 4 and
N/Nf = 1, 3, 5, and 7 particles per flavor. We carry out our calculations using
our recently proposed quantum Monte Carlo method on a nonuniform lattice. We
report on the ground-state energy and contact for a range of couplings, as
determined by the binding energy of the two-body system, and show explicitly
how the physics of the Nf-body sector dominates as the coupling is increased.Comment: 5 pages, 4 figure
