Collective excitations in Na sub(2)IrO sub(3)

We study the collective excitations of Na sub(2) IrO sub(3) in an itinerant electron approach. We consider a multi-orbital tight-binding model with the electron transfer between the Ir 5d states mediated via oxygen 2p states and the direct d-d transfer on a honeycomb lattice. The one-electron energy...
