In this article, we outlined the necessary steps in calculating the radial wavefunctions for the Hydrogen atom. Thus, the radial wavefunctions particularly , and are easily obtained  without bothering to normalize it.
We use the formula below to find the wavefunction,

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

In quantum mechanics, the perturbation theory is a very important mathematical tool which is used to approximate physical quantities that describe complicated quantum systems based on our knowledge on the simpler ones. It tells us how to correct the solutions to the unperturbed or undisturbed problem to approximately account for the [...]

In this post we investigate the properties of a quantum oscillator by using an algebraic tool in quantum mechanics called ‘ladder operators’. Using the ladder operator it becomes easy to find the following properties for a quantum oscillator in a given energy level:  the average position and momentum and the square of [...]

In quantum mechanics, I have learned that the wavefunctions, , reside in Hilbert’s space.  What is Hilbert’s space? I guess to answer this question requires exploring the basic  properties of Hilbert’s space.
Hilbert’s space is a linear vector space whose elements, entities or components obey certain rules or axioms.  This means firstly than [...]
