Knowledge
The student will be able to demonstrate advanced knowledge in Statistical Mechanics and in Field Theory. The student will be able to expose his knowledge in a short seminar toward the scientific community.In particular he will have knowledge about
phase transition and phenomena that present scaling behavior. The student will be
able to understand the analogies between Statistical Mechanics and the field theory
of elementary particle.
Assessment criteria of knowledge
The student will be assessed on his demonstrated ability to discuss the main
course contents using the appropriate terminology.
