Query: Mott Transition and Glassiness in the Face Centered Cubic Lattice   We study the half-filled Hubbard model on the geometrically frustrated face
centered cubic (FCC) lattice, using an auxiliary field based real space
technique. The low temperature state is a paramagnetic metal at weak
interaction, an antiferromagnetic insulator (AFI) with flux like order at
intermediate interaction, and an AFI with `C type' order at very strong
interaction. Remarkably, there is a narrow window between the paramagnetic
metal and the AFI where the system exhibits spin glass behaviour arising from
the presence of disordered but `frozen' local moments. The spin glass state is
metallic at weaker interaction but shows crossover to pseudogap behaviour and
an insulating resistivity with growing interaction. We compare our results to
available experiments on FCC and pyrochlore based materials and suggest that
several of these features are typical of three dimensional correlated systems
with geometric frustration.
