Commutes with translation
WebOct 15, 2024 · Which operators commute with the Hamiltonian? Since the Hamiltonian is the infinitesimal generator of time translation, it also means that the operator is constant in time. An operator commutes with Hamiltonian means we can simultaneously find the eigenstate of energy and the observable represented by that operator. WebIn mathematics, a binary operation is commutative if changing the order of the operands does not change the result. It is a fundamental property of many binary operations, and many mathematical proofs depend on it. …

We can also prove the following theorem: if two operators A^ and B^ commute, then they have common eigenfunctions. Proof: Let be an eigenfunction of A^ with eigenvalue a: A ^ = a 5

The vector w in Equation (7) represents translation on the points. Thus an affine transformation can always be decomposed into a linear transformation followed by a translation.
