How to show that the function is an eigenfunction of the operator?
Therefore, to determine if a wavefunction is an eigenfunction of the operator in question, all you have to do is operate on ψ(x) by ˆA and see if you get the function ψ(x) multiplied by a constant back.
There is no single ψ(x) of a free particle.
For a given linear operator T : V → V , a nonzero vector x and a constant scalar λ are called an eigenvector and its eigenvalue, respec- tively, when T(x) = λx.
For a given eigenvalue λ, the set of all x such that T(x) = λx is called the λ-eigenspace.

How do you check if a function is an eigenfunction?

If an operator turns a nonzero function into a multiple of that function, then that function is an eigenfunction of the operator, and the multiple is the eigenvalue.

What is the formula for eigenfunction?

In the study of signals and systems, an eigenfunction of a system is a signal f(t) that, when input into the system, produces a response y(t) = λf(t), where λ is a complex scalar eigenvalue.

1 Answer. To find its eigenfunction f, it is equivalent to solve Lf=λf, that is, d2fdx2=λf. This is an second order ODE with constant coefficient, which can be solved. After finding all the possible solutions for f, we can consider the normalized condition and initial conditions to find the specify f.
