Like.
Great question - and I genuinely wish I could contribute. I'd love to discuss it here on Physics Forums because honestly, this is... -

I have never seen that in any book. Unless you mean the drawing of the wave function, it's difficult to draw a complex function, so...

I think you meant to write:$$-\frac{\hbar^2}{2 m}\nabla^2\phi_n+V\phi_n=E_n\phi_n$$

bhobba reacted to JimWhoKnew's post in the thread Undergrad The imaginary part of the wave function with Like.
Introductory textbooks usually deal a lot with time-independent Hamiltonians of the form$$H=\frac{\mathbf{P}^2}{2 m}+V(\mathbf{x})\quad...

I don't see that at all. Consider, e.g., Griffiths & Schroeter, Introduction to Quantum Mechanics (3rd ed.) in which the authors solve...

I fail to see how RQM has any bearing on this. What you've written makes no sense to me, I'm sorry to say.

Skeptical.
If a negative energy appears somewhere, it is always an indication of a direction problem, or in other words a geometric problem, which... -

The following is taken from Bjorken and Drell, Relativistic Quantum Mechanics (1964), pp. 5-6: So the problem with the Klein-Gordon...

If doesn't work in relativistic context. For example, if you apply it to Klein-Gordon equation then probability is not conserved.

The main problem is how to define probability density for particle positions. QFT avoids that problem by saying that the theory at the...
