剪切驱动干扰中的粘性指数和非粘性指数

Dimensionality and viscosity exponent in shear-driven jamming

Peter Olsson

摘要:

在零温度下,在三维的双分散无摩擦粒子的收集模拟与剪切驱动的动力学,目的是在二维的行为进行比较。相反的流行的图片,并在对比的结果从各向同性干扰压缩或淬火,我们发现,在三维的临界指数是不同的,在二维和三维的剪切驱动的干扰属于不同的普适性类。

英文摘要:

Collections of bidisperse frictionless particles at zero temperature in three dimensions are simulated with a shear-driven dynamics with the aim to compare with behavior in two dimensions. Contrary to the prevailing picture, and in contrast to results from isotropic jamming from compression or quench, we find that the critical exponents in three dimensions are different from those in two dimensions and conclude that shear-driven jamming in two and three dimensions belong to different universality classes.
