| Research Abstract |
To discuss the supercooled liquid state on complex fluids like water, we perform generalized replica exchange method (gREM) computer simulations on model glass formers, 12-6 polydisperse Lennard-Jones system with a Gaussian size polydispersity at constant pressure. We obtain the preliminary gas-liquid-crystal-glass phase diagram of polydisperse LJ systems on temperature- size polydispersity plane at constant pressure not only between the triple point and the critical point, but also above the critical point. The gREM was created to study first order transitions. This simulation resutls suggest that it is a powerful algorithm for phase equilibrium on complex fluids in general.
