We investigate the glass and the jamming transitions of hard spheres in finite dimensions d, through a revised cell theory, that combines the free volume and the Random First Order Theory (RFOT). Recent results show that in infinite dimension the ideal glass transition and jamming transitions are distinct, while based on our theory we argue that they indeed coincide for finite d. As a consequence, jamming results into a percolation transition described by RFOT, with a static length diverging with exponent ν = 2/d, which we verify through finite size scaling, and standard critical exponents α = 0, β = 0 and γ = 2 independent on d.
我们通过改进的单元理论,即自由体积和随机一阶理论(RFOT)的组合,研究了有限维度 d 下硬球的玻璃化转变和堵塞转变。最近的结果表明,在无限维空间中,理想玻璃化转变和堵塞转变是不同的,而基于我们的理论,我们认为它们在有限维度 d 下确实是重合的。因此,堵塞转变导致了 RFOT 描述的渗流转变,静态长度随指数 ν = 2/d 发散,我们通过有限尺寸标度和标准临界指数 α = 0、β = 0 和 γ = 2 来验证这一点,这些指数与 d 无关。
