Harmonics Oscillator Homework: Solving Schrodinger Equation

Click For Summary
SUMMARY

The discussion centers on demonstrating that the function \(\psi_1 = N x e^{-\frac{x^2}{\sigma}}\) is an eigenfunction of the total energy operator \(H\) in the context of the Schrödinger equation for a harmonic oscillator. Participants clarify that the correct form of the equation to use is \(\frac{d^2\psi}{dy^2} + (e - y^2)\psi = 0\), where \(y = \sqrt{\frac{mw}{\hbar}} x\). The confusion arises from the need to correctly substitute \(\psi\) into the equation without introducing unnecessary \(x^2\) dependencies.

Homework Statement



Show:
[tex]\psi_1=N x e^{-\frac{x^2}{\sigma}}[/tex] is an eigenfunction of the total energy operator(H).

Homework Equations


psi=N x exp[-x^2/K]

The Attempt at a Solution


I plugged in the above to the Schrödinger Equation-time indep. for Harmonic oscillator but I keep getting an x^2 dependence inside the calculation. Do I not plug this in?

oh, I should be putting psi into d^2(psi)/dy^2 + (e-y^2) psi =0 where y=sqrt(mw/h) x. the asymtotic solution: e-->0. This is what is I should plug it into right?
