dc.description.abstractWe investigated the electronic structure of Na2IrO3 using optical spectroscopy, first-principles calculation, and x-ray absorption spectroscopy. We found that the electronic structure of Na2IrO3 is mainly determined by anisotropic hopping interactions and spin-orbit coupling. Due to the hopping interaction, the orbital character of the bands near the Fermi level deviates from the spin-orbit coupling-induced Jeff = 1/2 states. Polarizationdependent O 1s x-ray absorption spectroscopy showed that the Jeff = 1/2 state of an Ir atom can be mixed with the Jeff = 3/2 state of the neighboring Ir atom. This result implies that mixing between the Jeff = 1/2 and 3/2 states in the valence state should be carefully considered in proposed exotic states of Na2IrO3, such as topological insulator and quantum spin liquid states.-
