What wave structures correspond to real state functions in quantum physics?

[Ed Quanta]

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.

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.
