| Outline of Final Research Achievements |
We have developed first-principles computational methods to describe interactions between light pulses and materials based on time-dependent density functional theory. We have also developed a novel multi-scale simulation method combining dynamics of electrons and electromagnetic fields of light, and have succeeded to establish a theoretical basis to describe wide varieties of phenomena relevant to light-matter interactions. As interactions between extreme light pulses and solids, we have analyzed phenomena such as coherent phonon generations, ultrafast changes of dielectric properties, ultrafast electric currents which appear in transparent materials, variations in time of band gap of semiconductors, and the threshold and depth of ablations induced by femtosecond laser pulses.
