In classical mechanics; In quantum mechanics. Of course, this problem today appears far from being settled and is a heavy burden left us by . As he says it further: “These assumptions are reasonable on account of the eigenvalues of real linear operators being always real numbers”. First, the abstract definition: if T, L: V → V are linear operators on a vector space V over a field K, then L is said to be a ladder operator for T if there is a scalar c ∈ K such that the commutator of T and L satisfies. This question is hotly debated by people working in quantum optics, quantum computation and wherever foundations of quantum mechanics may enter. Physical meaning and relation to unitary transformations. These are some notes, mostly for my own benefit, on annihilation, creation, and ladder operators in quantum mechanics, with a few remarks towards the end on angular momentum, spin and Clebsch–Gordan coefficients. The book does not assume the reader is an expert in operator algebra, though some familiarity with quantum mechanics, quantum field theory and special relativity is a prerequisite. Topics here include: operator algebras (von Neumann, c* and w*), factors, positive linear forms and states, the GNS construction, nets of algebras of local observables and vacuum states. \displaystyle [T, L] := TL - LT = cL. The book is not aimed at experts in constructive or field theory and the algebra of local observables.
