 Synopsis:

The final goal of the course is to acquire advanced knowledge of Classical and Quantum Mechanics to design insilico 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 postprocessing softwares.
 Requirements:

Derivative of a function, definite and indefinite integral, Newton‘s equations, laws of thermodynamics, basic usage of a computer.
