In this video, I show you one last technique for solving the Dirac equation for relativistic Landau Levels, and that is the use of the power series method in cylindrical coordinates.
Clarification: By uncoupled, I don't just mean that there is no term in which k_z and m multiply each other. I am also referring to the fact that they multiply different alpha matrices. The relations satisfied by the alpha matrices ensure that cross terms don't show up. In this video, I only remembered to mention this at the very end.

Typo: At 5:43, it should be Y(l , m+½) = (Sqrt { [ ( 2l + 1 ) ÷ 4π ] ⋅ ( l − m − ½ )! ÷ ( l + m + ½ )! } )⋅[exp i(m+½)φ]⋅P(l , m+½) Annoying Ass Spinor Spherical Harmonics Identity | Quantum Mechanics](https://i.ytimg.com/vi/ssdQWpWru-E/mqdefault.jpg)
