PHYSICS OF THE IONOSPHERE AND PHYSICS OF THE MAGNETOSPHERE
(objectives)
Electromagnetic and corpuscular radiation of solar origin gives rise to complex interactions affecting the magnetosphere and the Earth's ionosphere. The magnetic fields of the Sun and the Earth play a fundamental role in these interactions, in a space characterized by the presence of partially ionized plasma (weakly ionized gas): here the physics of the propagation of radio waves is very interesting.
The aim of the course is to present a selection of the most relevant physical phenomena that unfold in this complex environment, where man deploys sophisticated technological systems, on whose functioning the structures of contemporary society are increasingly dependent. Space Weather deals with problems resulting from disturbances in the circumterrestrial environment, in particular consequent to the deterioration of the radiopropagative conditions of the ionosphere.
The ultimate goal is to bring the student closer to the physics of phenomena, stimulating his interest in research in the sector and projecting him towards contemporary challenges to be met.

STATISTICAL MECHANICS
(objectives)
The course aims to give an overview of modern developments in statistical mechanics. In particular, starting from the theory of phase transitions and critical phenomena, we want to show how the concepts underlying the method of the re-normalization group emerged. This method is now widely used in various fields of statistical mechanics. The critical phenomena constitute the classical application of the method, which is illustrated in detail in the first 6 credits of the course. These first 6 credits can therefore be used by multiple addresses. The remaining 2 credits focus on more recent applications of the method in the field of matter physics.
