Library for calculating energies and wavefunctions for spherically symmetric quantum-mechanical problems. Sometime in the future it might even live up to its name!

The scripts folder contains examples.

The library is divided into three parts, problems, bases and calculations. Each separated from the other so that you can choose a problem, which method to use and how to calculate the hamiltonian.

A problem is defined as potential, a characteristic mass and a factor that converts the energy from units of the problem to units of eV.

Two problems are included: the Hydrogen atom and the He5 core.

A basis module represents a basis to expand in. The basis expansion methods are essentially a function that takes row and column and returns the corresponding matrix element in the hamiltonian.

Two bases expansion methods are included: The isotropic harmonic oscillator and discretized momentum space.

Calculations are ways to calculate the hamiltonian, wavefunctions, etc. The simplest one is serial -- one at a time.

Will add ways to do this in parallel.
