摘要: Phase transitions are macroscopic phenomena which one should in principle be able to describe by equilibrium statistical mechanics. Progress has however been very slow this field over the past decades. This is particularly true for liquid-solid transition nevertheless a general property of matter. During present decade some progress achieved theoretical study freezing simple model systems such as hard sphere system. Analysis experimental 1 and computer simulation2 studies makes it moreover plausible that more realistic monitored underlying system so coexistence may soon also become accessible Considerable realized recent years theory reformulating pioneering (but unsuccessful) work Kirkwood Monroe into modern language density functional theory3. The original Monroe4 was formulated on basis Born-Green-Yvon hierarchy retrospect not good starting point since depends explicitly interaction potential whereas known2 largely independent details potential.
