The theory of finite-size scaling explains how the singular behavior of thermodynamic quantities in the critical point of a phase transition emerges when the size of the system becomes infinite. Usually, this theory is presented in a phenomenological way. Here, we exactly demonstrate the existence of a finite-size scaling law for the Galton-Watson branching processes when the number of offsprings of each individual follows either a geometric distribution or a generalized geometric distribution…

Finite-time scaling in local bifurcations

This work analytically derive finite-time scaling laws for two ubiquitous transitions given by the transcritical and the saddle-node bifurcation, obtaining exact expressions for the critical exponents and scaling functions.

Phase transition, scaling of moments, and order-parameter distributions in Brownian particles and branching processes with finite-size effects.

The problem of Brownian diffusion with drift is revisited in order to study finite-size effects in the geometric Galton-Watson branching process, and exact expressions for the Laplace transforms of the probability distributions and their first and second moments are obtained.

Field-theoretic approach to the universality of branching processes

Branching processes are widely used to model phenomena from networks to neuronal avalanching. In a large class of continuous-time branching processes, we study the temporal scaling of the moments of

Finite-size scaling is a key tool in statistical physics, used to infer critical behavior in finite systems. Here we use the analogous concept of finite-time scaling to describe the bifurcation

Dependence of exponents on text length versus finite-size scaling for word-frequency distributions.

Solid quantitative evidence is given for the validity of a finite-size scaling law for the text-length dependence of word-frequency distributions using both careful statistical tests and analytical arguments based on the generalized central-limit theorem.

Finite-time scaling for epidemic processes with power-law superspreading events.

Epidemics unfold by means of a spreading process from each infected individual to a variable number of secondary cases. It has been claimed that the so-called superspreading events of the COVID-19

Scale-free networks revealed from finite-size scaling

Finite size scaling provides a powerful framework for analyzing self-similarity and the scale free nature of empirical networks and is a useful tool for analyzing deviations from power law behavior in the vicinity of a critical point in a physical system arising due to a finite correlation length.

True scale-free networks hidden by finite size effects

Finite size scaling analysis of real networks finds that a large number of the networks follows a finite size scaling hypothesis without any self-tuning, which concludes that underlying scale invariance properties of many naturally occurring networks are extant features often clouded by finite size effects due to the nature of the sample data.

Finite-size scaling of survival probability in branching processes.

This work derives analytically the existence of finite-size scaling for the survival probability as a function of the control parameter and the maximum number of generations, obtaining the critical exponents as well as the exact scaling function, which is G(y)=2ye(y)/(e(y)-1), with y the rescaled distance to the critical point.

Finite Size Scaling and Numerical Simulation of Statistical Systems

The theory of Finite Size Scaling describes a build-up of the bulk properties when a small system is increased in size. This description is particularly important in strongly correlated systems where

We calculate the distribution of the size of the percolating cluster on a tree in the subcritical, critical, and supercritical phase. We do this by exploiting a mapping between continuum trees and
