Provide the fundamental principles of quantum mechanics, the most relevant results for atomic physics, nuclear and subnuclear physics, from historical, mathematical and physical point of view.

Knowledge of Classical Mechanics, of basic Maths and of Mathematical methods for Physics.

Frontal lessons using the blackboard with the integration of exercises and numerical simulations that require the active participation of the students.

Students with physical disabilities, Learning Disabilities or Special Education Needs can request specific services and tools via the Staff Sviluppo e Coordinamento Carriere e Servizi alle Studentesse e agli Studenti, consulting the University webpage: https://www.uniupo.it/en/services/servicesstudents- physical-or-learning-disabilities Students with disabilities, learning disabilities or special education needs, once they have contacted the University Staff, can refer to the tutor in charge of the course to define the examination modalities, concerning academic aspects.

The exam consists of an oral test during which the student will be asked to illustrate two or three themes chosen from the topics covered in class, posing the question from both a physical and mathematical point of view. To pass the test the student must demonstrate that they know and understand the basic concepts and their application to problem solving. A passing grade is achieved if at least two questions are answered satisfactorily. Honors are awarded if the answers to all questions are complete and exhaustive.
