May 27, 2022 at 10:44 comment added ZeroTheHero Some of the difficulties with the momentum and kinetic energy of the infinite well are discussed here physics.stackexchange.com/q/362305/36194 or in this well-known paper arxiv.org/abs/quant-ph/0103153 (arXiv version).
May 27, 2022 at 10:41 comment added ZeroTheHero The infinite well is a strange animal because the solution $\psi$ must be $0$ at the ends, and I would not trust a qualitative graphical method in this case. In cases other than the infinite well, $\psi(x)$ can extend smoothly and lazily in the classically forbidden region rather than be forced to $0$. In fact, if you solve (numerically) the finite well with a bump, I remember the probability would be larger in the shallower region (I have not done this in a while but that’s what I remember).
May 27, 2022 at 8:36 comment added jambajuice If you look at this link : theory.physics.manchester.ac.uk/~judith/AQMI/… , seems to be saying the opposite.
May 27, 2022 at 8:35 comment added jambajuice So just to also get this clear, if I were to have a particle in an INFINITE potential well between $x=0$ and $x=a$, and slightly perturb the inside, so that for $x>a/2$, we have a potential of $V_{0}$ - I expect the wavefunction to have a higher amplitude on the right?
