WebOct 9, 2024 · It is straightforward to verify that these satisfy J z z ± = ( ± ℏ / 2) z ± , making them eigenstates of J z, with eigenvalues ± ℏ / 2. However, they are not eigenstates of J … WebThat these eigenvalues assume the values specified in these identities is proven in considerable detail below. These eigenfunctions of L 2 and of L z will not, in general, be …
WebNote, that the differential operator which represents Lz only depends on the azimuthal angle φ, and is independent of the polar angle θ. It therefore: Here, the symbol ∼ just means … Webdetermine the eigenfunctions and eigenvalues of L^2. It is also easy to derive L^+L^ = L^2 L^2 z + hL^z; L^ L^+ = L^ 2 L^ z hL^z; and L^ 2= L^ z + hL^z +L^ L^+ = L^ z + hL^z +L^+L^ = L^2 z + 1 2 L^ L^ +L^ L^+ : Note: compare this with harmonic oscillator H^ = h! ^ay^a+ 1 2 . 2.1.3 Eigenvalues and eigenfunctions
WebThe eigenvalue (+1)2 is degenerate;thereexist(2+1) eigenfunctions corresponding to a given and they are distinguished by the label m which can take any of the (2 + 1) values m = ,−1,...,−, (8.23) In fact it is easy to show that m labels the eigenvalues of Lˆ z.Since Ym (θ,φ) ∼ exp(imφ), (8.24) we obtain ... WebThis result proves that nondegenerate eigenfunctions of the same operator are orthogonal. Two wavefunctions, ψ1(x) and ψ2(x), are said to be orthogonal if. ∫∞ − ∞ψ ∗ 1ψ2dx = 0. Consider two eigenstates of ˆA, ψa(x) and ψa (x), which correspond to the two different eigenvalues a and a ′, respectively.
