二维胶体晶体熔化的结构和动力学研究

our system,hexatic phase has strong dynamical heterogeneities which exhibit a nonmonotonic trend. Interestingly, the string-like structuresofcooperativeparticles are observed in hexatic phase. It is well known that the string-like structures are rearrangements regions occurred via the cooperative motion of spatially clustered particlesin supercooled or glass-forming liquids. In our view, these specialstructures of cooperative particlesplay an important role in melting behavior. Moreover, we study the melting of mixtures of soft and hard particles system. The cooperative motion regions show strong spatial correlation with defect clusters.二维胶体晶体熔化的结构和动力学研究英文摘要IIIKeywords: 2D melting; KTHNY; structure; dynamical heterogeneityWritten byXi HangboSupervised byZhang Zexin
