We investigate the properties of a simple quantum system consisting of a particle in a one-dimensional infinite square well potential.

Finding the eigenvectors and eigenvalues of the state of a quantum system is one of the most important concepts in quantum mechanics. And it is here where many students get confused.
In order to learn this by heart, one has to do several exercises.  There are many ways that can be employed when [...]

In an earlier post about the properties of Hermitian operators, it was noted that quantum operators of physical significance are Hermitian by type. Here we discuss more fully about Hermitian matrices.
A n x n matrix is Hermitian if it is equal to its corresponding adjoint matrix. Now, for each Hermitian matrix, it [...]
