实验室简介
软物质物理实验室主要研究领域是软凝聚态物理中的非晶态物质,包括颗粒物质,玻璃,泡沫,胶体等的材料属性、流变和非平衡态的特性。这些物质有显著的共性:在足够大的密度,足够低的温度,或足够小的外力下它们会由液态转变为固态(jamming transition),但是在结构上没有显著的变化。近期实验室拟开展的具体研究工作包括:1)胶体系统的临界尺度率和Jamming研究;2)软物质系统在极限条件下的屈服应力研究;3)无摩擦颗粒系统的剪切流变行为研究;4)Jamming系统的振动模式分

中国科大在低温结晶机理研究中取得新进展 中国科大物理学院、合肥微尺度物质科学国家研究中心徐宁教授研究组与复旦大学物理系谭鹏教授研究组合作,在低温结晶机理的相关研究中取得重要进展,相关成果2023年4月25日在线发表于《物理评论快报》(Physical Review Letters)。 结晶是复杂的非平衡动力学过程,其中包含了多种局域结构的时空演化。厘清各种结构之间的竞争、探讨促进和阻碍晶体生长的因素一直以来都是备受关注的前沿研究内容。经典成核理论给出了结晶成核的热力学图像,然而,近年来的研究表明,经典成核理论适用于结晶温度至动力学旋节线温度的“高温”区间,成核过程伴随着显著的粒子扩散运动。在动力学旋节线温度以下的“低温”区间,由于粒子扩散运动减慢,与晶体构型不匹配的二十面体结构也参与到了成核过程中,这些都是不利于成核的因素,因此,人们有理由认为晶体生长速率会变慢。然而,研究表明晶体生长速率反倒会在低于动力学旋节线温度的时候达到最大。此外,随着温度进一步降低至玻璃化转变温度附近,玻璃化会强烈阻碍晶体成核生长。因此,扩散、结构阻挫、玻璃化转变等因素的相互作用和竞争使得“低温”区间的
