摘要
The jamming transition of particles with finite-range interactions is characterized by a variety of critical phenomena, including power-law distributions of marginal contacts. We numerically study a recently proposed simple model of jamming, which is conjectured to lie in the same universality class as the jamming of spheres in all dimensions. We extract numerical estimates of the critical exponents, theta = 0.451 +/- 0.006 and gamma = 0.404 +/- 0.004, that match the exponents observed in sphere packing systems. We analyze finite-size 縮放律 effects that manifest in a subcritical cutoff regime and size-independent but protocol-dependent 縮放律 curves. Our results support the conjectured link with sphere jamming, provide more precise measurements of the critical exponents than previously reported
