Scope:
Stimulated by the recent development of strong laser systems, various optical phenomena driven by the interaction between a material and light have been reported so far. Strong terahertz, infrared, or visible pulses with stable carrier phase can not only simply vary the refractive index or the dielectric function but also enable us to see some novel optical phenomena such as phase change by controlling the electronic state of the material itself (e.g., photo-induced phase transition), optical nonlinear effect beyond the usual perturbation theory (e.g., higher harmonic generation), and so on. The dynamics of the excited electrons causing the interesting optical features has developed a new horizon of the optical researches and many materials have been widely studied from semiconductors to strongly correlated solids from the viewpoint. In this symposium, we notice the novel photonic effects (nonlinear optical effect including the higher harmonic generation, photo-induced phase transition, ultrafast phenomena, etc.) and discuss the recent theoretical and experimental progresses concerning those phenomena.
