Mechanism for subgap optical conductivity in honeycomb Kitaev materials

14 Apr 2018 Bolens Adrien Katsura Hosho Ogata Masao Miyashita Seiji

Motivated by recent terahertz absorption measurements in $\alpha$-RuCl$_3$, we develop a theory for the electromagnetic absorption of materials described by the Kitaev model on the honeycomb lattice. We derive a mechanism for the polarization operator at second order in the nearest-neighbor hopping Hamiltonian... (read more)
