Boron with STO6G

Variational Quantum Monte Carlo

Introduction   I’ll try to describe here briefly another project I have on GitHub1. There will not be much except links, but hopefully those will be useful. The project is far from being perfect, the simple averaging used there for example could be improved, as there are autocorrelations that one should be aware of, but … Read more

Cu band structure

Korringa–Kohn–Rostoker method

Introduction As I mentioned in the previous post, I already have a project on KKR on GitHub1. I won’t add here a lot of description, I’ll point you some references instead. Usually I also try to add links to some other projects that are small enough to be comprehensible in a reasonable time, this time … Read more


Augmented Plane Waves

Introduction Again, I have a new project on GitHub. It’s not so new, it was working already last year (the APW part) but I didn’t have the patience to write a description for it until now. Actually, there are two new projects on GitHub, related, but this post is about the Augmented Plane Waves1 one. … Read more

Diamond band structure

Tight Binding

Introduction There are many methods to calculate band structures of crystals. I implemented the Empirical Pseudopotential project, some of the code can be reused for other methods. One of the methods is simple and fast, the tight binding method, so I simply took the code from the last project, cut a part out and modified … Read more

DFT for a Quantum Dot

Introduction This post is describing another project that is leading (hopefully) towards something a little more serious: DFT Quantum Dot1. It will be a very short description because it’s Sunday. As usual, here is the program in action: It displays the quantum dot ‘orbitals’ with VTK volume rendering. Do not assign much physical reality to … Read more
