Deriving hermite differential equation from schrødinger harm oscillator

Click For Summary
SUMMARY

The discussion focuses on deriving the Hermite polynomial from the Schrödinger equation for a harmonic oscillator. The user attempts to solve the problem but encounters an error in calculating the second derivative, specifically ##\frac{\partial^2 \psi}{\partial y^2}##. A suggestion is made to revisit this calculation to ensure all terms are included, which is crucial for obtaining the correct Hermite differential equation.

PREREQUISITES
  • Understanding of the Schrödinger equation
  • Familiarity with harmonic oscillators in quantum mechanics
  • Knowledge of Hermite polynomials

Seems like your mistake lies in your calculation of ##\frac{\partial^2 \psi}{\partial y^2}##. I suggest that you check again on this point to see whether you had left out one term.
 
thanks!
