Plans for the fourth week, Feb 10-14

Dear all, welcome back to FYS4411.

The plans for this week are 

Topics.

• Short repetition from last week

• Mathematical and computational details of importance sampling and Fokker-Planck and Langevin equations

• For the lab session we will continue our discussions on how to build a VMC code for project 1

The jupyter-notebook is attached and we will cover some of the mathematical details on how to compute the trial wave functions with importance sampling as well as the more mathematical (technicalities) of importance sampling such as the Fokker-Planck equation and how we  derive the actual expression for the quantum force.

You can also find the jupyter-notebook at https://github.com/CompPhysics/ComputationalPhysics2/blob/gh-pages/doc/pub/week4/ipynb/week4.ipynb

To read more about Metropolis, Markov Chains, importance sampling, Fokker-Planck and Langevin equations, we recommend Becca and Sorella's text sections 3.4-3.9 and 4.2-4.4.

Best wishes to you all,

Morten
