The course describes the basic principles of quantum mechanics, its physical motivations, its mathematical formalisms, its main applications to atomic and molecular physics, to gases and condensed matter.
It is expected that the student will have a good knowledge of the main quantum phenomena in atoms, molecules, gas and solids.
It is expected that the student will acquire a familiarity with the basic principles which characterize the quantum description of physical phenomena and an understanding of the physical contexts in which such description is required. It is also expected that he will learn to solve simple problems involving quantum particles or simple quantum mechanical systems.
Traditional lectures for 70 hours.
The course, after an introduction about the early stages of the discovery of quantum theory and the description of the so-called old quantum theory, describes the formalism of modern quantum theory and the simplest applications of Schroedinger equation to atomic and molecular physics.

MODERN PHYSICS
The exam is divided into two parts, written and oral.
The written test consists of several questions or problems regarding topics covered during the course: to each question, a score is assigned and explicitly specified on the exam sheet. The sum of the scores of all the questions is 33/30. To have access to the oral exam a minimum total score of 18/30 is required.
The details of the exam modalities are illustrated to the students in class at the beginning of the course.
The questions of the written exams are of variable difficulty, in order to achieve an accurate evaluation of the competence achieved by the student.
The oral exam is lead by the professor responsible for the course and by another expert, who is usually a professor of the department of physics. The length of the oral exam varies from 30 to 50 minutes. The oral exam is divided into two parts: the first part is a discussion of the written test, in particular of the questions or the points which have not been correctly or completely answered by the student. The second part consists of a question on a topic which is different from the ones of the written test. The student is asked to present a topic covered in the course and lecture about it on the blackboard in his own personal way, in order to evaluate his abilities of synthesis and of personal elaboration. The score of the oral exam, maximum 6/30, is added to the score obtained in the written test to obtain the final score.
