Course „Atomistic simulations of solids and nanostructures” is dedicated to the introduction in modern methods aimed at the simulations of the properties of solids at the macro- and nanoscales. The course includes lecture part in which the basics of theoretical methods of atomistic simulations are covered, as well as the practical part, which consists of a number of problems dealing with the simulation of various properties of solids.
