Interplay between Hund's coupling and spin-orbit interaction on elementary excitations in Sr2IrO4
Jun-ichi Igarashi, Tatsuya Nagao
We study the elementary excitations in 5d transition metal oxideSrIrO by calculating the particle-hole Green's function within the random phase approximation on an antiferr…
Magnetic excitation in resonant inelastic x-ray scattering of SrIrO: A localized spin picture
Jun-ichi Igarashi, Tatsuya Nagao
We study the magnetic excitations in 5d transition-metal oxide SrIrO on the basis of the Heisenberg model with small anisotropic terms on a square lattice. We calculate the…
Strong coupling theory of spin and orbital excitations in Sr2IrO4
Jun-ichi Igarashi, Tatsuya Nagao
We study the low-lying excitations in 5d transition-metal oxide Sr_2IrO_4 on the localized electron picture. We find that Hund's coupling together with the spin-orbit interaction l…
Elementary excitations probed by L-edge resonant inelastic x-ray scattering in systems with weak and intermediate electron correlations
Jun-ichi Igarashi, Tatsuya Nagao
We develop a formalism to calculate the L-edge resonant x-ray scattering (RIXS) spectra from transition-metal compounds. Using a multi-orbital tight-binding model, we derive useful…
