Simulation Methods in Physics II SS 2012

Overview

Type

Lecture (2 SWS) and Tutorials (2 SWS)

Lecturer

Prof. Dr. Christian Holm, (Lecture); Olaf Lenz, Peter Košovan, Florian Dommert, Georg Rempfer, Tobias Richter (Tutorials)

Course language

English

Lectures

Time: Thursdays, 11:30 - 13:00, Room V 57.06

Tutorials

Time: Wednesday, 14:00-15.30, 2 hours, Room U 104

The lecture is accompanied by hands-on-tutorials which will take place in the CIP-Pool of the ICP, Pfaffenwaldring 27, U 104. They consist of practical exercises at the computer, like small programming tasks, simulations, visualization and data analysis. The tutorials build on each other, therefore continuous attendance is expected.

Scope

The course intends to give an overview about modern simulation methods used in physics today. The stress of the lecture will be to introduce different approaches to simulate a problem, hence we will not go too to deep into specific details but rather try to cover a broad range of methods. For an idea about the content look at the lecture schedule.

Prerequisites

We expect the participants to have basic knowledge in classical and statistical mechanics, thermodynamics, electrodynamics, and partial differential equations, as well as knowledge of a programming language (preferably C or C++). The knowledge of the previous course Simulation Methods I is expected.

Certificate Requirements

1. Attendance of the exercise classes

2. Obtaining 50% of the possible marks in the hand-in exercises

There will be a final grade for the Module "Simulation Methods" (this module consists of both lectures, Sim I plus Sim II) determined at the end of lecture Simulation Methods II.

The final grade will be determined in the following way: There will be an oral examination performed at (or after) the end of the course Simulation Methods II (SS 2011).

Useful online resources

• E-book: D.P. Landau and K. Binder: A guide to Monte Carlo Simulations in Statistical Physics

• Linux cheat sheet here (53 KB).

• A good and freely available book about using Linux: Introduction to Linux by M. Garrels

• Not so frequently asked questions about GNUPLOT (Often used by myself as a cheat sheet)

• Introduction to Molecular Simulation and Statistical Thermodynamics (pdf textbook from TU Delft)

• Short introduction to shell scripting (bash)

• A more detailed introduction to bash scripting

• Be careful when using Wikipedia as a resource. It may contain a lot of useful information, but also a lot of nonsense, because anyone can write it.

Tutorials

Scheduling of tutorials

New worksheets are handed out every two weeks (see the list below). The following week is dedicated to working on problems related to the last worksheet. Homework in the form of a report should be sent to the tutors before the next worksheet is handed out. The two-week cycle ends with the discussion of results of the previous worksheet and handing out a new one.

Tutorial 1 - Error analysis and correlations

Tutorials in 2012 are mostly based on the ones from previous year. Updated worksheets will be made available online on the day when they should be handed out. If you want to take a look ahead and see what is coming, have a look at the worksheets from the previous year.

Obtaining extra points

The first person who identifies a bug in the code provided by the tutors gets an extra point and one additional extra point if he/she can fix the bug. The same applies to finding a mistake in the worksheets which significantly changes the meaning. We are also thankful for pointing out misprints, but these are not awarded extra points.

Guidelines for submitting tutorial reports

Same as as in the previous semester.
