A recent paper by Denton et al. revealed an interesting fundamental relationship between the eigenvalues and eigenvectors of a matrix. I will describe their findings and explore how it might be applied.

In this post I will extend the previously presented simple Schrödinger equation solver using the concepts of linear operators and closures.

In this post I will present a simple solver of the Schrödinger equation in python based on a real space formulism.

Recently, I have written a utility program for managing namelist based input in Fortran. I will describe the motivation for this program and demonstrate its utility in application.

Scientific software needs to print out information during the course of a run. In this post, I will describe three key features that program output should have, and compare various output formats by this rubric.
