Is Angular Momentum Operator Hermitian?
Is Angular Momentum Operator Hermitian? are also Hermitian. This is important, since only Hermitian operators can represent physical variables in quantum mechanics (see Sect. 4.6). Is the momentum operator Hermitian? The momentum operator is always a Hermitian operator (more technically, in math terminology a “self-adjoint operator”) when it acts on physical (in particular, normalizable) quantum
