Description:  Aims: The aim of this unit is to provide students with experience in the application of some of the major techniques used in the simulation of physical systems, and to develop their ability at using computers in physical modelling. Topics will be chosen for study to encourage a greater understanding of both the model and the underlying physics. The emphasis will be on the application and interpretation of the techniques, not on programming. Learning Outcomes: After taking this unit the student should be able to: * identify issues which influence the choice of programming environment, language and architecture; * write and develop C# code for computer simulations, including interfacing to a 2d graphics package; * outline applications of two of the following four topics: (i) diffusion limited aggregation; (ii) the Ising model; (iii) molecular dynamics; and (iv) polymers and protein folding; * for each of the two topics, outline the physics and computational issues and explain the methodology and output of the simulations performed. Skills: Written Communication T/F A, Numeracy T/F A, Data Acquisition, Handling, and Analysis T/F A, Information Technology T/F A, Problem Solving T/F A. Content: C# programming basics. Two projects are assigned to each student from the following four topics: Latticebased simulations: Diffusion limited aggregation as a physical model for growth processes. Investigation of properties of clusters formed by DLA. Effects of varying the growth rule. Molecular dynamics: Overview of contemporary applications. Application to multiparticle 2d LennardJones system. Numerical solution of equations of motion. Potential cutoff. Calculation of observables; temperature, pressure, diffusion coefficient, structural information including pair correlation function g(r). Monte Carlo simulation in statistical physics: The Ising model. Revision of elementary statistical physics. Revision of Monte Carlo methods. Importance sampling. Markov states. Metropolis algorithm. Computation of thermal averages; magnetisation, energy density, specific heat, susceptibility. Spin correlation function. Polymers and Protein Folding Hydrophobicpolar protein folding model on a 2d lattice. This model captures an essential feature of protein structures, namely the core of a folded protein typically consists of residue with hydrophobic side chains which cluster together and exclude water. The aim is to explore move types and interactions between the chain components.
