Prerequisites:

Knowledge of elements of elementary quantum mechanics.
Knowledge of elements of elementary Statistical Mechanics
(distribution functions, statistical ensembles, ensemmble
averages, etc.) 
Target skills and knowledge:

Fundamental concepts of Solid State Physics and
connections between the microscopic physical laws
and the experimentally measurable properties.
Capability to solve problems that involve the properties
of condensed matter.
Capability of applying to real systems simple
predictive models that embody properties of
condensed matter systems on the microscopic scale. 
Examination methods:

Oral exam 
Assessment criteria:

Adequate comprehension and global knowledge of
concepts and arguments described throughout the
course.

Planned learning activities and teaching methods:

Lectures with the use of conventional blackboard and
projector for transparencies.
On a weekly basis, simple problems about
arguments covered during the classes will be
handed to the students, to be solved
on their own within a few days. 
Additional notes about suggested reading:

Photocopies of the slides shown during the classes (in electronic pdf format) will be given to the students.
