| Research Abstract |
Toward the ultimate goal to have "ideal glass", in which molecules are frozen in an irregular manner at equilibrium, we have analyzed various mathematical models within a framework of equilibrium statistical mechanics that connect atomic level descriptions with macroscopic states of matter. As the result, we have found a finite dimensional model that exhibits the emergence of macroscopic overlap. While the transition of this model seems to be of the first-order with latent heat, we also find another model that exhibits Random First Order Transition without latent heat. These two results are the first report in the world, and they will provide a significant step toward deep understanding of realistic glasses.
