Explore the fundamentals of rotations in quantum mechanics, focusing on infinitesimal rotation operators, orbital angular momentum as a generator of rotations, and the proof of commutation relations among angular momentum components. This lecture covers:
Rotation about the z-axis and generalization to arbitrary axes
Taylor expansion of rotation operators
Derivation of the commutation relation [Lx, Ly] = iℏLz.
Perfect for MSc Physics students and anyone studying Dirac equation, quantum angular momentum, and symmetry operations.
