摘要：

Through the mapping onto the kinetic lattice gas model the dynamical density functional equation is solved by the Monte Carlo method in a deeply supercooled hard-sphere liquid, while focusing on how the system explores the free-energy landscape during a relaxation process. A variety of metastable states appear as the supercooling proceeds beyond the equilibrium crystallization point. Our approach is the first to reproduce the hopping transitions among these states as a solution of a mesoscopic kinetic equation.
