各向同性势单组分体系的超脆性玻璃动力学:扩散与阻挫的竞争
Superfragile glassy dynamics of onecomponent system with isotropic potential: competition of diffusion and frustration
摘要:
采用分子动力学模拟方法研究了宽密度范围内单组分三维粒子质点系体系通过对排斥势相互作用的玻璃态动力学性质。玻璃态是超脆性的,具有很高的玻璃形成能力。玻璃化转变温度Tg在阻挫最大的密度处具有明显的最小值。
英文摘要:
We investigate glassy dynamical properties of one component three-dimensional system of particles interacting via pair repulsive potential by the molecular dynamic simulation in the wide region of densities. The glass state is superfragile and it has high glassforming ability. The glass transition temperature Tg has pronounced minimum at densities where the frustration is maximal.
