Computational Physics blog
This post contains both theory and programming.
Introduction This is an intermediate post between the one on the Monte Carlo methods and one presenting a Monte Carlo C++ program I intend to write. My goal is to briefly expose the theory here – most of it with links – and provide a very easy JavaScript example for the Metropolis algorithm applied on … Read more
Introduction This is an important branch of computational physics and hopefully I’ll have several programs to post on this topic. I’m quite sure I’ll post at least one. I’ll write here some theoretical things briefly describing the methods, to be referenced later. But before going into that, I’ll point to a book on Computational Physics1 … Read more
Introduction Finally here1 it is. A simple (relatively) program implementing the Numerical Renormalization Group. I tried to implement it as simple as possible to be easy to understand. Here is the program in action, running an Anderson model at half-filling: I already used charts generated by the program in The Kondo Effect and Renormalization Groups … Read more
Introduction The first post on this blog dealt with Newtonian mechanics, it seems natural to follow it with another big name in physics and another important field. So here it is, something linked to Maxwell and with his equations. Something still simple for now, a program to visualize the electric field in 2D. Here is … Read more
Introduction Newton is considered as being the one that started the modern physics, so something related with his work seems appropriate to start this blog. Besides, I had an old program simulating a solar system that I wrote quite a while ago. I wrote the program with the old OpenGL fixed pipeline and leapfrog integration, … Read more
