Outline of Final Research Achievements

Although the study of the glass transition of the supercooled liquids has a long history but even the mean-field picture has not been completely established yet. In this project, we have implemented extensive simulations and theoretical analysis in order to verify one of the most promising scenario of the glass mean field theory, called the RFOT. More specifically, (1) we established that the RFOT can quantitatively verify the relationship between the glass transition for liquids and the jamming transition for hard spheres, (2) we extended the so-called inhomogeneous mode-coupling theory to the system in the vicinity of the higher order singularity point, and (3) we have done the simulation for a cluster glass phase of the quasi-long ranged "ultra-soft" potential model fluids.
