  In this paper, we propose a map which connects nucleons bound in nuclei and
Ising spins in Ising model. This proposal is based on the fact that the
description of states of nucleons and Ising spins could share the same type of
observables. We present a nuclear model as a correspondence to an explicit
modified Ising model and qualitatively confirm the correctness of this map by
simulation on a two-dimensional square lattice. This map would help us
understand the profound connections between different physical systems.
