Monte Carlo Methods

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 moreMonte Carlo Methods

The Numerical Renormalization Group

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 moreThe Numerical Renormalization Group

Newtonian Gravity

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 moreNewtonian Gravity
