Scaling behaviour under the influence of a homogeneous size-dependent perturbation
arXiv:2303.01874 · doi:10.5488/CMP.26.13101
Abstract
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 then illustrated using three concrete problems for which exact results are obtained.
