WitrynaInstead, we recall that the key property of the adjoint (and the transpose, for real matrices) was how it interacts with dot products. In fact, handling matrices in dot products is essentially the whole reason for doing adjoints/transposes. So, we use this property as the definition of the adjoint: the adjoint AH is the linear operator such that, Witryna18 gru 2024 · Understand the properties of a Hermitian operator and their associated eigenstates; Recognize that all experimental obervables are obtained by Hermitian operators; Consideration of the quantum mechanical description of the particle-in-a-box exposed two important properties of quantum mechanical systems.
