The applications of interest of ordinaruy quantum mechanics require familiarity with specific techniques for the study of systems with many degrees of freedom. The main purpose of this course is poroviding the student with the basic ideas of these techniques and illustrating the relevant applications, both in a many-body, non relativistic context and in the context of the relativistic extension of quantum physics. AIMS AND CONTENT LEARNING OUTCOMES Providing the student with basis concepts in relativistic electrodynamics, and with quantum mechanics of many-body systems in the context of second quantization. AIMS AND LEARNING OUTCOMES The student will extend and upgrade his/her knowledge in quantum mechanics The second quantization formalism will be illustrated in details and applied to relevant physical situations, both in non-relativistic and relativistic cases. The quantization of electromagnetic fields and the relativistic description of quantum mechanics in simple cases will also be discussed. PREREQUISITES Classical physics Non-relativistic quantum mechanics Special theory of relativity TEACHING METHODS Traditional lectures at the blackboard; six hours per week. SYLLABUS/CONTENT 1.
