ABSTRACT
As a prelude to solving specific problems, let us discuss a few general properties of operators. Recall that the Hermitian adjoint, B†, of an operator B is defined as the operator whose matrix elements are given by () https://www.w3.org/1998/Math/MathML"> 〈 Ψ | B † | Φ 〉 ≡ 〈 Φ | B | Ψ 〉 * , https://s3-euw1-ap-pe-df-pch-content-public-u.s3.eu-west-1.amazonaws.com/9780429499265/ff9ae276-bf0f-4700-9154-eaa3ea82fbc6/content/eq511.tif" xmlns:xlink="https://www.w3.org/1999/xlink"/>
