WebThe value of the observable for the system is then the eigenvalue, and the system is said to be in an eigenstate. Equation 3.3.8 states this principle mathematically for the case of energy as the observable. WebNov 8, 2024 · Indeed, an eigenstate of an observable will yield an eigenvalue equation not only with the operator associated with that observable, but also with any function of that operator. Let's show this for the simple case of the square of an operator.
