Query: Experimental Electronic Structure of the Metallic Pyrochlore Iridate
  Bi2Ir2O7   Angle-resolved photoemission measurements have been performed on Bi2Ir2O7
single crystals, a prototypical example of the pyrochlore iridates. The density
of states, the Fermi surface, and the near Fermi level band dispersion in the
plane perpendicular to the (111) direction were all measured and found to be in
overall agreement with our LDA + SOC density functional calculations. Our
observations indicate the general validity of the LDA + SOC-based approach for
the electronic structure of pyrochlore iridates, raising the possibility that
some of the novel predicted phases such as quantum spin ice or Weyl Fermion
states may exist in this family of compounds.
