Prerequisites:

Statistical Mechanics 
Target skills and knowledge:

Thermodynamics of phase transitions. Mean field techniques. Transfer matrix approaches to 1d systems. Scaling theory and renormalisation group techniques for critical phenomena, 
Examination methods:

Written exam with some problem to be solved and some questions on the theory.
Oral exam. 
Assessment criteria:

The positive valuation of the student will be based on her/his capability in understanding the main basic concepts presented in the course and on her/his ability in solving problems using the methodologies and analytical tools presented during the lectures. 
Course unit contents:

Thermodynamics of phase transitions. Critical points, order parameters and critical exponents. Phase transitions and spontaneous symmetry breaking. Entropyenergy argument and the lower critical dimension. Ising model. Analytical tools to solve spins model in 1D, transfer matrix formalisms. Mean field theory. Variational theory. Landau theory. Ginzburg Landau theory. Ginzburg criterium and upper critical dimension. Scaling theory and r scaling relations between critical exponents. Homogeneity and scaling: Kadanoff block spin argument, Renormalisation group in real space. Universality. Spontaneous symmetry breaking for continuous symmetry. Goldstone's theorem. 
Planned learning activities and teaching methods:

During the lectures will be presented and solved some standard problems for this course. 
Additional notes about suggested reading:

Some note of the course will be available.
