Fluctuation-induced first-order superfluid transition in unitary $\mathrm{SU}(N)$ Fermi gases
Functional renormalization group calculation shows fluctuation-induced first-order superfluid transition in unitary SU(N) Fermi gases for N >= 4, with predictions for critical temperature and discontinuities in gap and entropy.
