Computational Methods in Modern Physics

Course Description

Different computing methods used for simulations in contemporary physics problems are presented through four topics. Ray tracing in curved spacetime: Spacetime. Curved spacetime. Metric. Path length. Riemannov tensor. Einstein s equation and spherically symmetric solutions. Light propagation in curved spacetime. Numerical solutions of differential equation. Ray-tracing. Gravitational lens. Application of machine learning to event classification in high energy physics: Introduction to ground-based gamma-astronomy: observed objects and instruments. Data acquisition and analysis chain. Event reconstruction. Problem of signal separation in the presence of high levels of noise. Application of random forest algorithm to the gamma-hadron separation problem in high energy physics. Atomic bonds in molecules and solids: quantum-mechanical model and classical approximation. Crystal lattice. Material surface adsorption: chemisorption and physisorption. Van der Waals material layers (graphen as an example). Finding optimal structure by quantum-mechanical simulation and/or using classical approximation. Calculation of ionizing radiation shields by fast engineering methods. Green's function method for point and distributed radiation sources. Build-up factor for gamma radiation inside shields. Green's function for removing fast neutrons in water. Diffusion approximation of the neutron transport equation and some of its applications.
