A wave function which satisfies the above equation is said to be normalized. Wave functions that are solutions of a given Schrodinger equation are usually orthogonal to one another. Wave-functions that are both orthogonal and normalized are called or tonsorial.

First, a small (but important) correction: two wave functions ψ1 and ψ2 are called orthogonal to each other if ∫¯ψ1ψ2dτ=0, Wave functions are complex-valued functions and complex-conjugation of the first argument is important. 1. So, yes, orthogonality is a not a property of a single wave function.

The physical meaning of their orthogonality is that, when energy (in this example) is measured while the system is in one such state, it has no chance of instead being found to be in another. Thus a general state’s probability of being observed in state n upon making such a measurement is c∗ncn.

My current understanding of orthogonal wavefunctions is: two wavefunctions that are perpendicular to each other and must satisfy the following equation: ∫ψ1ψ2dτ=0. From this, it implies that orthogonality is a relationship between 2 wavefunctions and a single wavefunction itself can not be labelled as ‘orthogonal’.

The physical meaning of the wave function is an important interpretative problem of quantum mechanics. The standard assumption is that the wave function of an electron is a probability amplitude, and its modulus square gives the probability density of finding the electron in a certain location at a given instant.

Normalizing a wavefunction just means multiplying it by a constant to ensure that the sum of the probabilities for finding the particle equals 1. Mathematically, this means integrating the function over all space so as to make the probability 1.

Degenerate eigenfunctions are not automatically orthogonal, but can be made so mathematically via the Gram-Schmidt Orthogonalization. The proof of this theorem shows us one way to produce orthogonal degenerate functions. then ψa and ψ″a will be orthogonal.

Orthogonal states in quantum mechanics In quantum mechanics, a sufficient (but not necessary) condition that two eigenstates of a Hermitian operator, and , are orthogonal is that they correspond to different eigenvalues. This means, in Dirac notation, that if and. correspond to different eigenvalues.

A useful property of the energy eigenstates is that they are orthogonal, the inner product between the pure states associated with two different energies is always zero, .

Thus, if Aψa(x)=aψa(x), where a is a complex number, then ψa is called an eigenstate of A corresponding to the eigenvalue a. so the variance of A is [cf., Equation ([e3. 24a])] σ2A=⟨A2⟩−⟨A⟩2=a2−a2=0.

Eigenvalues are a special set of scalars associated with a linear system of equations (i.e., a matrix equation) that are sometimes also known as characteristic roots, characteristic values (Hoffman and Kunze 1971), proper values, or latent roots (Marcus and Minc 1988, p. 144).
