Dynamics of an Exciton-phonon Triangle under Photoirradiation
Noriyuki Aoyagi, Hiroaki Matsueda, Kunio Ishida
Herein, the dynamics of excitons coupled with optical phonons in a triangular system is numerically studied. By representing the excitons by quasi-spin states, the similarity betwe…
Two-step dynamics of photoinduced phonon entanglement generation between remote electron-phonon systems
Kunio Ishida, Hiroaki Matsueda
The generation of quantum entanglement between phonons in photoirradiated remote electron-phonon systems is numerically studied. Upon excitation by a visible/ultraviolet laser puls…
Interplay of electron-phonon nonadiabaticity and Raman scattering in the wavepacket dynamics of electron-phonon-photon systems
Kunio Ishida
Ultrafast wavepacket dynamics of electron-phonon-photon systems is studied by numerical calculations. When nonadiabaticity of electron-phonon systems is taken into account, Raman s…
Doping-Induced Alterations in Electronic Structure of Copper Oxide Superconductors and a New Horizon for Higher Tc materials
Hiroshi Kamimura, Jaw-Shen Tsai, Osamu Sugino +2
By paying special attention to the fact that the doped holes induce deformation of CuO6 octahedrons (or CuO5 pyramids) in cuprate superconductors, we develop a non-rigid band theor…
Quantum pattern formation dynamics of photoinduced nucleation process
Kunio Ishida, Keiichiro Nasu
We study the dynamics of quantum pattern formation processes in molecular crystals which is a concomitant with photoinduced nucleation. Since the nucleation process in coherent reg…
Nonlinearity in the dynamics of photoinduced nucleation process
Kunio Ishida, Keiichiro Nasu
Nonlinear dynamics of photoinduced cooperative phenomena is studied by numerical calculations on a model of molecular crystals. We found that the photoinduced nucleation process is…
