Query: Orbital magnetism of ultracold fermionic gases in a lattice: dynamical
  mean-field approach   We study finite-temperature properties of ultracold four-component mixtures
of alkaline-earth-like atoms in optical lattices that can be effectively
described by the two-band spin-$1/2$ Hubbard model including the Hund's
exchange coupling term. Our main goal is to investigate the effect of exchange
interactions on finite-temperature magnetic phases for a wide range of lattice
fillings. We use the dynamical mean-field theory approach and its real-space
generalization to obtain finite-temperature phase diagrams including
transitions to magnetically-ordered phases. It allows to determine optimal
experimental regimes for approaching long-range ferromagnetic ordering in
ultracold gases. We also calculate the entropy in the vicinity of
magnetically-ordered phases, which provides quantitative predictions for
on-going and future experiments aiming at approaching and studying long-range
ordered states in optical lattices.
