Discussion Overview

The discussion revolves around the nature of wave structures corresponding to real state functions in quantum physics. Participants explore the implications of real-valued wave functions, particularly in relation to physical phenomena and specific quantum mechanical systems.

Discussion Character

  • Exploratory
  • Technical explanation
  • Conceptual clarification

Main Points Raised

  • One participant questions the meaning of "wave structure" and requests clarification on the terminology used.
  • Another participant notes that a real wave function Q(x) has a structure such that the average momentum is zero.
  • A participant suggests that the inquiry pertains to the space-dependent part of the wave function, indicating that real-valued wave functions are associated with specific quantum systems like the step potential, infinite well, finite well, harmonic oscillator, and hydrogen atom.

Areas of Agreement / Disagreement

The discussion does not reach a consensus, as participants express differing levels of understanding and interpretation of the initial question and the concept of wave structures.

Contextual Notes

Participants express uncertainty regarding the terminology and the specific aspects of wave functions being discussed, indicating a need for clearer definitions and context.

What type of wave structure does a real state function correspond to? I am sorry. I meant to post this in the Quantum physics section.

What's a "wave structure"?
 
Please , restate your question more specifically.

what do You mean. The expressions you are using are very strange to say the least. :confused: :-p

A wave function Q(x) which is real has a structure such that the average momentum is zero.

[I'm using Q(x) to represent the wave function in position space because there's no psi on my keyboard and 'w' which most looks like psi I use for eigenvalues]

What type of physical phenomena is described by a real valued wave functon?

Since the time-depedent part is always complex, I'm assuming you mean the space-dependent part. In that case, you have only to look up the chapter on stationary state problems in any elementary QM textbook. You will find that the step potential, the infinite well, the finite well, the harmonic oscillator all have real-valued space wavefunctions. The hydrogen atom also has some purely real spatial wavefunctions.
