Quantum mechanics for the nucleus?

How come I never see any equivelant of the particle in the box or harmonic oscillator counterparts for modeling of the atomic nucleus? I'm still a bit new to QM, but the only thing I ever see are QM descriptions of electrons, electron orbitals, electron spins, electron quantum entanglement, electron double slit, etc. Nothing ever for protons, gluons, etc., except for the nuclear shell model maybe, but nothing in-depth even on that. Can you even apply the Shrodinger equation to a proton? I've never seen it. Any references would be great.

You can do this, but the nuclear potential is not as easy as the coulomb potential, and you do not get analytic solutions for the eigenstates.
It is even worse if you look inside the proton, with the strong interaction and its self-interaction you need quantum field theory for an appropriate description.
 
Can you even apply the Shrodinger equation to a proton?
it will be better to use dirac eqn since proton is spin 1/2 but it only applies to structurelss particle like electron so it will not give useful results.

Believe me, any book on nuclear physics will provide an answer to your question, in great detail.
 
Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. Towards the end of the first lecture for the Qiskit Global Summer School 2025, Foundations of Quantum Mechanics, Olivia Lanes (Global Lead, Content and Education IBM) stated...

If we release an electron around a positively charged sphere, the initial state of electron is a linear combination of Hydrogen-like states. According to quantum mechanics, evolution of time would not change this initial state because the potential is time independent. However, classically we expect the electron to collide with the sphere. So, it seems that the quantum and classics predict different behaviours!
According to recent podcast between Jacob Barandes and Sean Carroll, Barandes claims that putting a sensitive qubit near one of the slits of a double slit interference experiment is sufficient to break the interference pattern. Here are his words from the official transcript: Is that true? Caveats I see: The qubit is a quantum object, so if the particle was in a superposition of up and down, the qubit can be in a superposition too. Measuring the qubit in an orthogonal direction might...
