| The [[Ising model]] is a prototypical model in [[statistical physics]]. The model consists of discrete variables that represent magnetic dipole moments of atomic "spins" that can be in one of two states (+1 or −1). The spins are arranged in a graph, usually a lattice (where the local structure repeats periodically in all directions), allowing each spin to interact with its neighbors.

| [[Birman–Schwinger principle]] <small>(Eigenvalue transformation method)</small>

| In [[mathematics]] the Birman–Schwinger principle is a useful technique to reduce the eigenvalue problem for an unbounded differential operator (such as a [[Schrödinger operator]]) to an eigenvalue problem for a bounded integral operator. It originates from independent work by [[Mikhail Shlyomovich Birman|M. Sh. Birman]] and [[Julian Schwinger|J. Schwinger]] in 1961.
