Exchange operator
text:
In quantum mechanics, the exchange operator P ^, also known as permutation operator, is a quantum mechanical operator that acts on states in Fock space. The exchange operator acts by switching the labels on any two identical particles described by the joint position quantum state | x 1, x 2 ⟩. Since the particles are identical, the notion of exchange symmetry requires that the exchange operator be unitary.
