I heard that angular momentum operators and their eigenvectors are realted to SO(3) or SU(2)
group. Does anyone know a good textbook which explain the connection between how group theory and quantum mechanics (especially angualr momentum). I'm interested rather in books which emphasizes mathematical aspects and are quite precise in this matter.

I think the two old books by Rose and Edmonds are still the best for this.
I don't remember their exact titles but they have "angular momentum" in them.
 
Check out the book by Fonda and Ghirardi: "Symmetry Principles in Quantum Physics".
 
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!
