通过解析求解全复制对称性破缺标度方程,证明了堵塞转变中临界指数满足 a+b=1 的恒等式,从而统一了力学边缘稳定性与全复制对称性破缺理论。

摘要:

在无限维稠密硬球的全复制对称性破缺(fullRSB)解中,Charbonneau、Kurchan、Parisi、Urbani 和 Zamponi(CKPUZ;J.Stat.Mech.P10009, 2014)引入了三个临界指数 $a$、$b$、$c$,它们控制着堵塞转变附近 fullRSB 轮廓的匹配区域。这些指数满足两个标度关系。第一个关系 $b=(1+c)/2$ 已通过标度假设中的扩散-漂移平衡解析建立。第二个关系 $a+b=1$ 在数值上被观察到具有任意精度,但一直未能证明。标度 fullRSB 假设中的指数 $a,b,c$ 与物理指数 $\alpha, \theta, \kappa$ 相关,后者通过关系 $\alpha=a/b$、$\theta=(c-a)/(b-c)$、$\kappa=c+1$ 控制间隙、力和重叠分布。关键在于,关系 $a+b=1$ 导出了标度关系 $\alpha=1/(2+\theta)$ 和 $\kappa=2-2/(3+\theta)$,这些关系由 Wyatt 及其合作者基于力学边缘稳定性论证独立预测。本文从标度 fullRSB 方程给出了恒等式 $a+b=1$ 的解析证明。该证明通过与 Claude(Sonnet 4.6 和 Opus 4.7)的交互获得,并由我们验证。

英文摘要:

Within the full replica-symmetry-breaking (fullRSB) solution of dense hard spheres in infinite dimension, Charbonneau, Kurchan, Parisi, Urbani, and Zamponi (CKPUZ; J.Stat.Mech.P10009, 2014) introduced three critical exponents $a$, $b$, $c$ governing the matching region of the fullRSB profile near the jamming transition. These exponents satisfy two scaling relations. The first, $b=(1+c)/2$, was established analytically by the diffusion-drift balance in the scaling ansatz. The second, $a+b=1$, was observed numerically to arbitrary precision but could not be proven. The exponents $a,b,c$ of the scaling fullRSB ansatz are related to the physical exponents $α, θ, κ$ that control the gap, force, and overlap distributions by the relations $α=a/b$, $θ=(c-a)/(b-c)$, $κ=c+1$. Crucially, the relation $a+b=1$ yields the scaling relations $α=1/(2+θ)$ and $κ=2-2/(3+θ)$ predicted on independent grounds by the mechanical-marginal-stability arguments of Wyart and collaborators. Here, we give an analytic proof of the identity $a+b=1$ from the scaling fullRSB equations. The proof was obtained through interaction with Claude (Sonnet 4.6 and Opus 4.7) and verified by us.
