| Outline of Final Research Achievements |
It is required to evaluate accurately van der Waals’s forces (dispersion forces) in a material such as molecular crystal, for the analysis of material properties. Our group has developed a new van der Waals spin density functional first in the world, which is capable of accepting magnetic materials. To capture properties of the new functional, we practically carried out the analysis of electronic structures in a pair of oxygen molecules and in solid oxygens, and optimized the atomic structures for them. Furthermore, we performed several applications to oxygen systems under an extremum state condition, such as under high pressure or under high magnetic field, and to some other systems.
