Ah, you're right. That's what I was looking for!

comment Non-separable solution for the Schrödinger equation
But does this cover all cases of non-separable solutions? Or are there solutions that cannot be represented as a linear combination of simple separable solutions?

comment What's wrong with the square root version of the Klein-Gordon equation?
And the most "perfect" version is just QFT which doesn't even really have a Schrodinger equation, right?

comment What's wrong with the square root version of the Klein-Gordon equation?
So essentially, this whole derivation involving squaring is just a heuristic to come up with an equation that is then checked with experiment to see how well it matches up? Is that why the Dirac equation is an "alternative" relativistic form of the Schrodinger equation?

comment What's wrong with the square root version of the Klein-Gordon equation?
Very helpful answer. Your last example -- would that imply that the series expansion (in matrix representation) of the time evolution operator U = exp(-iHt/ћ) is nonlocal as well, if H involves the gradient?

comment What's wrong with the square root version of the Klein-Gordon equation?
As you pointed out, since squaring two sides of an equation is not an equivalence operation, in what sense then is it valid to do that with the above?
