The final goal of the course is to acquire advanced knowledge of Classical and Quantum Mechanics to design in-silico experiments within the Materials Science field. At the end of the course, the students will know: - the fundaments of thermodynamics, newtonian and statistical mechanics, and how the relative formalism is implemented in order to calculate thermodynamical properties; - how the Schrödinger equation is setup and solved in order to calculate physical quantities; - how to combine the classical and quantum mechanics to model experimental results; and - a general protocol through which to design new materials at the atomic scale. By means of simulation laboratory experience, the students will eventually learn how to setup and run simulations, and how to analyse and present the results by using post-processing softwares.


The aim of this course is to give an advanced knowledge of the principles and techniques of computational materials science. At the end of the course, the student will be able to setup simulations to study atomic-scale material properties and to lay the foundations of a material design project; eventually, the student will gain the proper background to extend her/his own academic formation towards postdoctoral or industrial positions. The course covers the physical understanding of matter from an atomic point of view. Topics covered include static and dynamical description of matter at the atomic level. The course is tailored for PhD students with basic knowledge of laws of thermodynamics and Newton's laws. Fundamental theories in solid state physics are introduced together with their software implementation, showing how to use them in current-day technology, industry, and research. The course has a theoretical lecture component and laboratory experiences, making extensive use of examples and exercises to illustrate the material.
