How do we show that the greatest accuracy in the |mn> state is |n| = m for the Mx and My components?
 
Physics news on Phys.org
If M is an angular momentum operator, then Mx and My =0 for |n|=m.
 
Yes M is an angular momentum operator. I also know that the components Mx and My do not commute. However, I do not understand how to show the greatest accuracy.

Are you saying that Mx and My are orthogonal since they do not commute?

Thread 'Quantum behaviour of an electron around a positively charged sphere'

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!
