Abstract
We investigate multicomponent fermions in a flat band and predict
experimental signatures of nonFermi liquid behavior. We use dynamical
meanfield theory to obtain the density, double occupancy and entropy in
a Lieb lattice for $\mathcal{N} = 2$ and $\mathcal{N} = 4$ components.
We derive a meanfield scaling relation between the results for
different values of $\mathcal{N}$, and study its breakdown due to
beyondmean field effects. The predicted signatures occur at
temperatures above the Néel temperature and persist in presence
of a harmonic trapping potential, thus they are observable with current
ultracold gas experiments.
