Electronic structures of spin-orbit-coupled metal candidate PbRe2_2O6_6: one dimensionality and molecular orbital formation

This first-principles study reveals that the electronic structure of the spin-orbit-coupled metal PbRe2_2O6_6 is characterized by highly anisotropic quasi-one-dimensional Fermi surfaces and nearly dispersionless molecular-orbital-induced flat bands, which together provide a microscopic explanation for its experimentally observed anisotropic transport and successive phase transitions.
