Quantum SHO Wave Functions not Complex?

Click For Summary
SUMMARY

The discussion centers on the nature of solutions to the Schrödinger equation for the Quantum Simple Harmonic Oscillator (SHO), specifically addressing the Hermite Polynomials, which are real functions. It clarifies that while Hermite Polynomials themselves are real, the complete energy eigenstates include a time-dependent phase factor, represented as Ψ_n(x,t) = ψ_n(x) e^{-iE_n t / \hbar}. This phase factor introduces the necessary complex component to the wave function, resolving the initial confusion regarding the requirement for complex solutions.

The Hermite Polynomials are solutions to the Schrödinger equation for the Quantum Simple Harmonic Oscillator. But the Hermite Polynomials are real, not complex. I thought that solutions to the Schrödinger equation always had to be complex. What am I not understanding? Thanks in advance.

You're missing the time-dependent phase factor. Energy eigenstates generally look like this, in their time-dependent form:

\Psi_n(x,t) = \psi_n(x) e^{-iE_n t / \hbar}
