Photoinduced magnetic bound state in itinerant correlated electron system with spin-state degree of freedom
Yu Kanamori, Jun Ohara, Sumio Ishihara
Photo-excited state in correlated electron system with spin-state degree of freedom is studied. We start from the two-orbital extended Hubbard model where energy difference between…
Optical manipulation of magnetism in spin-charge coupled correlated electron system
Jun Ohara, Yu Kanamori, Sumio Ishihara
Photoirradiation effects in correlated electrons coupled with localized spins are studied based on the extended double-exchange model. In particular, we examine melting of an antif…
Photo-induced spin-state change in itinerant correlated-electron system
Y. Kanamori, H. Matsueda, S. Ishihara
Photo-induced spin-state change in itinerant correlated-electron system is studied. The model Hamiltonians before and after photon-pumping are derived from the two-orbital Hubbard…
Numerical Study of Photo-Induced Dynamics in Double-Exchange Model
Y. Kanamori, H. Matsueda, S. Ishihara
Photo-induced spin and charge dynamics in double-exchange model are numerically studied. The Lanczos method and the density-matrix renormalization-group method are applied to one-d…
Dynamical coupling and separation of multiple degrees of freedom in a photoexcited double-exchange system
Y. Kanamori, H. Matsueda, S. Ishihara
We present a theory of ultrafast photo-induced dynamics in a spin-charge coupled system, motivated by pump-probe experiments in perovskite manganites. A microscopic picture for mul…
