Polarized Atoms Visualized by Multipole Moments
Polarized Atoms Visualized by Multipole Moments
An ensemble of spin-polarized atoms is characterized by its density matrix , which can be decomposed into atomic multipole moments that transform under rotations as irreducible tensors of rank . This Demonstration gives a graphical visualization of the longitudinal multipole moments (left) and of the corresponding populations of the magnetic sublevels (right).
