大质量平面FK-Ising模型中费米观测量的收敛性

Convergence of Fermionic Observables in the Massive Planar FK-Ising Model

S. C. Park

摘要:

我们证明收敛的2-和4-点费米子可观的FK-伊辛模型的简单连接的区域离散的平面等径晶格在大规模(近临界)的标度极限。前者也被称为大规模接口的(费米子)鞅可观测(MO),特别是封装界面的边界访问概率。后者编码连接概率在4点交替(广义Dobrushin)边界条件,其精确收敛,然后进一步分析,以产生交叉估计一般边界条件。值得注意的是,我们得到了一个巨大的版本的所谓的Russo-Seymour-Welsh(RSW)型估计等径晶格。这些可观的满足大量版本的s-全纯性[Smi 10],我们开发了强大的技术来利用这个条件,不需要任何正则性假设的域或特定方向的扰动。由于许多其他近临界观测量满足相同的关系(参见。[BeDu 12,CIM 21,Par 19]),这些策略在更广泛的背景下的大规模模型分析中直接使用。

英文摘要:

We prove convergence of the 2- and 4-point fermionic observables of the FK-Ising model on simply connected domains discretised by a planar isoradial lattice in massive (near-critical) scaling limit. The former is alternatively known as a (fermionic) martingale observable (MO) for the massive interface, and in particular encapsulates boundary visit probabilties of the interface. The latter encodes connection probabilities in the 4-point alternating (generalised Dobrushin) boundary condition, whose exact convergence is then further analysed to yield crossing estimates for general boundary conditions. Notably, we obtain a massive version of the so-called Russo- Seymour-Welsh (RSW) type estimates on isoradial lattice. These observables satisfy a massive version of s-holomorphicity [Smi10], and we develop robust techniques to exploit this condition which do not require any regularity assumption of the domain or a particular direction of perturbation. Since many other near-critical observables satisfy the same relation (cf. [BeDu12, CIM21, Par19]), these strategies are of direct use in the analysis of massive models in broader setting.
