摘要:

我们表明,在连续极限流域划分流域的Schramm-Loewner演变(SLE)曲线,被描述为一个单一的参数$κ$。几个数值评估,以确定这一点。所有的计算结果都与SLE $_κ$一致,其中$κ=1.734\pm0.005$是唯一已知的具有$κ<2$的SLE的物理实例。这超出了著名的对偶猜想,提出了关于对偶模型的存在性和可逆性的新问题。此外,它构成了一个强有力的指示共形不变性随机景观,并建议流域可能对应于一个对数共形场论(CFT)与中心荷$c\approx-7/2$。

英文摘要:

We show that in the continuum limit watersheds dividing drainage basins are Schramm-Loewner Evolution (SLE) curves, being described by one single parameter $κ$. Several numerical evaluations are applied to ascertain this. All calculations are consistent with SLE$_κ$, with $κ=1.734\pm0.005$, being the only known physical example of an SLE with $κ<2$. This lies outside the well-known duality conjecture, bringing up new questions regarding the existence and reversibility of dual models. Furthermore it constitutes a strong indication for conformal invariance in random landscapes and suggests that watersheds likely correspond to a logarithmic Conformal Field Theory (CFT) with central charge $c\approx-7/2$.
