Eigenvalue for 1D Quantum Harmonic Oscillator

Click For Summary
SUMMARY

The discussion focuses on demonstrating that the function u(q) = A (1 - 2q²) e^(-q²/2) is an eigenfunction of the Hamiltonian operator for the one-dimensional quantum harmonic oscillator (QHO), defined as &hat;H_{QHO} = &hat;p²/(2m) + (1/2)mω²x². Participants clarify that an eigenfunction of an operator yields the original function multiplied by a constant, known as the eigenvalue, when the operator is applied. The momentum operator is represented as -iħ(d/dx), which is crucial for the calculations involved.

Homework Statement



Show that the following is an eigenfunction of \hat{H}_{QHO} and hence find the corresponding eigenvalue:

u(q)=A (1-2q^2) e^\frac{-q^2} {2}


Homework Equations



Hamiltonian for 1D QHO of mass m
\hat{H}_{QHO} = \frac{\hat{p}^2}{2m} + \frac{1}{2} m \omega^2 x^2

Not sure about any others

The Attempt at a Solution



I don't know where to start

What means that a function is an eigen-function of some operator? Doesn't this mean that when you act with that operator on that function, the result will be the original function multiplied by a constant (where this constant is the eigenvalue)?

So, try to operate with HQHO on u(q) and see what happens!(the momentum operator is repsresented by -i\hbard/dx)
