AngularQM vs Learn Quaternions
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
AngularQM
This app helps quantum mechanics physicists quickly obtain matrix representations of angular momentum operators. It calculates matrices for J squared, the z component of J, and ladder operators for chosen total angular momentum values.
- Matrix representation of angular momentum operators
- Calculates J squared matrices
- Calculates Jz component matrices
- Calculates ladder operator matrices (J+, J-)
- Supports various total angular momentum values (j)
- Visualizes matrix representations

AngularQM is an application for physicists working in quantum mechanics. It allows quickly obtain the matrix representation of the operators involved in the construction of angular momentum in quantum mechanics. Once the total angular momentum of the quantum system under consideration has been chosen (j = 1/2, j = 1, j = 2, etc.) it is possible to calculate the matrices associated with the operator J squared and the z component of operator J. It is also possible to calculate and visualize the matrix representations of the ladder operators: J + and J-.
