comment WKB method of approximation
Yes there should. Good catch. Thanks Fabian. I see so only a classical approximation. Interesting.

Oops yeah. No I have the ground-state energy. I already calculated that. I'll see what I can come up with. Thanks for the help.

Ok. My math is a bit weak I guess. I'm having trouble translating this into anything worthwhile. I have a volume $$V = 4 \pi r*(b-a)$$ and energy $$E_0$$. How would I calculate the pressure? Thanks for the answer by the way. It makes sense when you see the change in ground-state energy.

Hmm. I don't quite understand what you mean when you say, "The pressure follows from equating the energy increase to the integral of PdV." Can you clarify this for me? Is P the pressure and V the volume of the annular container?

Particles don't like to be trapped and exert a sort of pressure on their boundaries. The force tries to push the boundaries out such that the particle is free.

It looks like I want to use the variational principle. I'm still curious If its possible with WKB though.
