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-.
