In this chapter we will discuss the basic theory of angular momentum which plays an extremely important role in the study of quantum mechanics. We will first define the angular momentum operator through the classical relation L = r × p and replace p by its operator representation -i [see ...
Consequently one always generalizes the Cartesian prescription to other coordinates and falls in a trap. In this work we introduce the difficulties one faces when the question of the momentum operator in spherical polar coordinate comes. We have tried to point out most of the elementary quantum ...
Angular momentum eigenfunctions Because the angular momentum operators derived above correspond to three‐dimensional rotations, it is natural to seek their eigenfunctions in spherical coordinates. After the transformation from Cartesian to spherical coordinates, the total momentum operator and the Z proj...
The chapter also discusses the Eigenvalues of the angular momentum. To determine the eigenvalues of the component, in some direction, of the angular momentum of a particle, it is convenient to use the expression for its operator in spherical polar coordinates, taking the direction in question as...
The super angular momentum, generators of the super-rotation, is realized as differential operators acting on functions defined on E(3|2). By solving the eigenvalue problem in spherical coordinates, a set of pseudo-orthonormalized functions is constructed, the super-spherical harmonics Ylmj, whose...

11.39) in xyz coordinates. Like the angular momentum vector, the components ω of the angular velocity vector in the xyz system are related to those in the primed system (ω′) by the expression ω′=Qω The inverse relation is simply (11.46)ω=Q−1ω′=QTω′ Substituting this into ...
We show that, under asymmetric filtering produced by this layer, gravity waves of low spherical order that are stochastically excited at the base of the convection zone of late-type stars can extract angular momentum from their radiative interior. The timescale for this momentum extraction in a ...
He has a Masters in Education, and a Bachelors in Physics. Cite this lesson Angular momentum is used to describe a rotating motion while linear momentum is concerned with translating motion. Learn more about the definitions of angular and linear momentum, and also the two different equations ...
