Weekly update FYS3150/4150

First, thx to everybody for heroic efforts with project 3. We really appreciate this! 

Here's a short update on plans for this week, week 43. 

We will discuss project 4, scroll down http://compphysics.github.io/ComputationalPhysics/doc/web/course to project 4, and the theory needed. This is largely covered by chapter 12 of the lectures notes, with an emphasis on

Markov chains and the Metropolis algorithm and chapter 13 on statistical physics. 

The model we will study is the famous Ising model, a model which has been widely used to study interacting systems, from studies of phase transitions to even analysis of elections in political science and sociology.  The model, its two-dimensional variant has also analytic solutions, thanks to Lars Onsager. 

The main theory is covered chapter 12 on Markov chains. We will discuss these topics during our lectures on Thursday and Friday. 

At the lab, we will mainly work with project 4. Best wishes to you all and thx again for great answers to project 3.

Anders, Anna, Mathias, Morten and Sebastian
