| Research Abstract |
We have developed a new computational code for quantum transition based on QED (Quantum Electrodynamics). We have applied it for studies of chirality and frequency dispersion of dielectric constant, and obtained new insights. As for the chirality study, using model molecules, we havestudied how chiral and achiral structures react on circularly polarized photon, through the quantities like the spin torque density, and have shown the clear difference between them. For the study of dielectric constant, its local frequency dependence of simple atoms is shown. We distribute our program code in our web site.
