TL;DR

This work presents an exact solution of a one-dimensional Ising chain with both nearest-neighbor and random long-range interactions and confirms the mean-field character of the transition.

Abstract

We present an exact solution of a one-dimensional Ising chain with both nearest-neighbor and random long-range interactions. Not surprisingly, the solution confirms the mean-field character of the transition. This solution also predicts the finite-size scaling that we observe in numerical simulations.
