SUMMARY:Kinetic magnetism of fermions in triangular lattices - Eugene Deml

DESCRIPTION:I will discuss recent progress of the optical lattice emulator
 s of the Fermi Hubbard model. The new feature of these experiments is avai
 lability of snapshots of many-body states with single particle resolution.
  I will summarize new insights from these experiments on the properties of
  doped Mott insulators in square and triangular lattices. Emphasis of the 
 talk will be on kinetic magnetism for the Fermi-Hubbard models in triangul
 ar type lattices. In the the regime of strong local repulsion between ferm
 ions\, magnetic interactions arise from propagation of charge carriers in 
 the Mott insulating state. In the case of hole doping\, antiferromagnetic 
 polarons originate from kinetic frustration of individual holes in a trian
 gular lattice. In the case of electron doping\, Nagaoka type ferromagnetic
  correlations are induced by propagating doublons. I will discuss applicat
 ions of these results to both TMDC moire materials and ultracold atoms in 
 optical lattices.
