For particle in the box wave function, it is the eigenfunction of kinetic energy operator but not the eigenfunction of momentum operator. So, do these two operators commute? (or it has nothing to do with commutator stuff?)
How about for free particle? For free particle, the wave function is eigenfunction of both kinetic energy operator and momentum operator. So, does it mean these two operators do not commute?
