comment Quantum Physics question
It looks like the factor involving θ is a function that has equal positive and negatives bits, so it all integrates to zero. For example, h[0, 0, 1, 0] has a Cos[θ] Sin[θ] factor. Changing the range to {θ, 0, π/2} gives something more interesting, but I have no idea if that is a sensible thing to do for the problem.

comment Weird results of calculating a sum of binomials?
Put a GenerateConditions -> True in your sum and it will tell you when the answer is valid.

You have an ampersand in the wrong place. You need SortBy[# , #[[2]] &]&

comment Adjusting contrast of a color scale with ListDensityPlot
Have you tried different colour schemes? Maybe "Rainbow" or "BrightBands". Have you tried a gamma correction instead of a log? Have you tried a ListContourPlot and specify the contours you want?

They are not the same if you define something for f. Try it with, say, f = #+1&.

comment Where does this gray solid line come from in plot?
I have expanded my comment into an answer. I agree that it is a good question. The simple answer is just one of those things you remember with experience.
