In this video, I show you how to solve the Schrodinger equation for a particle confined to a 2-sphere space.

There is a typo in the spherical harmonics normalization constant. In the second fraction under the square root, the 1's are supposed to be l's.

*I realize that a sphere is technically the surface of a ball, and so saying "the surface of a sphere" is not technically perfect.
*I also realize that the formula for the orbital-angular-momentum-squared operator given at the end should have a prefactor of "negative h-bar squared". That formula itself isn't used for anything in the calculation, so this error in no way effects the calculation.

$How To Solve The Dirac Equation For The Hydrogen Atom | Relativistic Quantum Mechanics In this video, I show you how to solve the Dirac Equation for the one electron atom. The process used consists of separation of variables, and then a power series treatment of the radial equation. The angular equation is then solved by constructing simultaneous eigenstates of spin and orbital angular momentum. These are called spinor spherical harmonics.
