lol. The answer was stupid/trivial for part c. It is apparently as if the crystal is an endless string of delta potentials - aka it looks like a string of delta potentials from - infinity to infinity because the wave function will continue to traverse the circle without 'realizing' it has...

Homework Statement Hey, the question is about delta function potentials V(x) = -g[... del(x + 3b/2) + del(x + b/2) + del(x - b/2) ...] going on out to a large x in either direction. a) sketch the ground-state wave fn, write the form of psi(x) for -b/2 to + b/2 b) show that e^z =...
