Plans for the week of February 9-13

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 for this week is at at https://github.com/CompPhysics/ComputationalPhysics2/blob/gh-pages/doc/pub/week4/ipynb/week4.ipynb (alternatively you can use the pdf file) 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.

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,

Aleksander and Morten
