Quantum Scattering

Introduction I have a project on GitHub about Quantum Scattering1 on a Lennard-Jones potential. The idea is from chapter 2 of a book2 I already mentioned on this blog. For this project I won’t put theory here, but refer you to the book instead. It’s a very good book, it’s worth having. I don’t know … Read moreQuantum Scattering

Chaos

Introduction People never cease to amaze me. By that I mean both laymen and ‘scientists’. I’ve seen many opinions of laymen about some sort of a ‘balance’ existing in all sorts of systems that no knowledgeable individual could claim to be in equilibrium. I’ve seen pretenses that the evil and sinning humans are ‘disrupting’ that … Read moreChaos

Poisson

Solving Poisson Equation

Introduction When I started this blog I already expected to have projects that use the Fast Fourier Transform. I actually wrote down several topic ideas for the blog, both solving the Poisson equation and the subject this post will lead to were there, too. I already mentioned in the Relaxation Method post that one can … Read moreSolving Poisson Equation

Nuclear Magnetic Resonance and Fourier Transform

Introduction I needed to use Fast Fourier Transform for a project that I’ll implement (hopefully) for this blog. Something quite different from the theme of this post, but I won’t reveal it. Depending on my free time and mood, I might have it working in a week or I might even drop it. I do … Read moreNuclear Magnetic Resonance and Fourier Transform

Lattice Boltzmann Density

Lattice Boltzmann

Introduction It’s time for an easier topic than the last time. I noticed – but I also expected it – that I have more success with projects like the Solar System than with a project like the Numerical Renormalization Group. There are mainly two reasons for it: it looks more spectacular to see a 3D … Read moreLattice Boltzmann
