Scaling behaviour under the influence of a homogeneous size-dependent perturbation

open access: yesCondensed Matter Physics, 2023
We study the finite-size scaling behaviour at the critical point, resulting from the addition of a homogeneous size-dependent perturbation, decaying as an inverse power of the system size. The scaling theory is first formulated in a general framework and

Finite size scaling of domain chaos [PDF]

open access: yesPhysical Review E, 2001
Numerical studies of the domain chaos state in a model of rotating Rayleigh-Benard convection suggest that finite size effects may account for the discrepancy between experimentally measured values of the correlation length and the predicted divergence near onset.

Finite-size correlation length and violations of finite-size scaling [PDF]

open access: yesThe European Physical Journal B, 2001
We address the problem of the definition of the finite-volume correlation length. First, we study the large-N limit of the N-vector model, and we show the existence of several constraints on the definition if regularity of the finite-size scaling functions and correct anomalous behaviour above the upper critical dimension are required.

Non-equilibrium relaxations: ageing and finite-size effects

open access: yesCondensed Matter Physics, 2023
The long-time behaviour of spin-spin correlators in the slow relaxation of systems undergoing phase-ordering kinetics is studied in geometries of finite size.

Deconfined Quantum Criticality, Scaling Violations, and Classical Loop Models

open access: yesPhysical Review X, 2015
Numerical studies of the transition between Néel and valence bond solid phases in two-dimensional quantum antiferromagnets give strong evidence for the remarkable scenario of deconfined criticality, but display strong violations of finite-size scaling ...

Anisotropic scaling of the two-dimensional Ising model II: surfaces and boundary fields

open access: yesSciPost Physics, 2020
Based on the results published recently [SciPost Phys. 7, 026 (2019)], the influence of surfaces and boundary fields are calculated for the ferromagnetic anisotropic square lattice Ising model on finite lattices as well as in the finite-size scaling ...

Finite-size-scaling functions for 3d O(4) and O(2) spin models and QCD [PDF]

open access: yes, 2001
We calculate numerically universal finite-size-scaling functions for the three-dimensional O(4) and O(2) models. The approach of these functions to the infinite-volume scaling functions is studied in detail on the critical and pseudocritical lines.

Boundary effects on finite-size scaling for the 5-dimensional Ising model

open access: yesNuclear Physics B, 2021
High-dimensional (d≥5) Ising systems have mean-field critical exponents. However, at the critical temperature the finite-size scaling of the susceptibility χ depends on the boundary conditions.

Finite-size scaling of meson propagators [PDF]

open access: yesNuclear Physics B, 2002
Using quenched chiral perturbation theory we compute meson correlation functions at finite volume and fixed gauge field topology. We also present the corresponding analytical predictions for the unquenched theory at fixed gauge field topology. These results can be used to measure the low-energy parameters of the chiral Langrangian from lattice ...
