Syllabus


Educational Objectives:
The course aims to transmit knowledge and skills to the student, the acquisition of which will be verified during the exam.

1. Knowledge and understanding: This course aims to instill a body of facts, principles, theories, and practices related to Modern Physics. Students will learn about the experiments and empirical observations that led to the formulation of Quantum Physics.

2. Applying knowledge and understanding: Students will develop the necessary skills and proficiency to apply their knowledge to solve specific tasks. This includes applying quantum principles to various fields such as atomic and molecular physics, condensed matter, quantum optics, and laser physics.

3. Making judgments (autonomy of judgment): The course will foster the ability to critically evaluate and interpret the concepts of Quantum Physics and their implications in various domains.

4. Communication skills: Students will enhance their ability to effectively communicate complex Quantum Physics concepts, both orally and in written form.

5. Learning skills: The course will equip students with the ability to further their understanding of Quantum Physics independently, fostering lifelong learning in the field.


Basic concepts of quantum mechanics and electrodynamics.

Upon completion of this course, students will have a foundational understanding of the key physical phenomena associated with the transition from Classical to Quantum Physics, a shift that heralded the advent of Modern Physics. Specifically, students will be able to: - Contextualize the pivotal milestones of this transition from a historical perspective. - Describe the novel physical hypotheses introduced, their formalism, significance, and the impact they had on previously established concepts. - Elucidate the groundbreaking experiments that paved the way for the evolution of Modern Physics.

Lectures


.

The oral exam, structured in the form of an interview following the discussion of a topic chosen by the student, includes a minimum of three questions and has an average duration of about 20-25 minutes. The purpose is to assess the level of knowledge of the exam subjects, the mastery of specialized language, and the ability to develop a critical reasoning about the discussed experiment and its theoretical implications. The exam is based on two topics agreed upon with the instructor.
The evaluation grid used is as follows:
- Excellent (30 - 30 with honors): excellent knowledge of the topics, excellent language skills, excellent analytical ability; the student is able to brilliantly analyze the discussed scientific case.
- Very good (27 - 29): good knowledge of the topics, notable language skills, good analytical ability; the student is able to correctly analyze the discussed scientific case.
- Good (24 - 26): good knowledge of the main topics, adequate language skills; the student shows an adequate ability to analyze the discussed scientific case.
- Satisfactory (21 - 23): the student does not show full mastery of the main topics of the course, although possessing fundamental knowledge; shows satisfactory language skills and sufficient ability to analyze the discussed scientific case.
- Sufficient (18 - 20): minimal knowledge of the main topics of the course and technical language, limited ability to adequately analyze the discussed scientific case.
- Insufficient: the student does not possess an acceptable knowledge of the discussed scientific cases.

This course explores topics closely related to one or more goals of the United Nations 2030 Agenda for Sustainable Development (SDGs)
