The PhD in Physics aims at training young physicists capable of successfully tackling modern research topics and therefore ready to undertake an academic career or enter the social world with the skills necessary to guide the transition to innovation, sustainability and to cooperation at every level. To this end, the course provides advanced knowledge, trains in laboratory work and in the collaboration within research groups and prepares young people with strong communication skills for the transfer of knowledge and scientific dissemination. The first year of the course is dedicated to training on specific topics, ranging from the physics of fundamental interactions, both theoretical and experimental, to the physics of condensed matter, complex and biological systems, up to applications in the astro-particle physics and in material science. PhD students are free to choose national and international advanced courses provided by ours or other universities or research institutes. Each PhD student follows a detailed program, agreed with a supervisor and approved by the Teaching Board. The second and third years are dedicated to research activity with the supervision of a scientific advisor and possibly a co-supervisor. At the end of the second year, each PhD student illustrates the scientific activities carried out, the results obtained and possible future developments in a formal seminar. Participation in seminars and conferences is strongly encouraged, as is collaboration and scientific exchange with other prestigious research groups. At the end of the third year, the doctoral student writes the doctoral thesis which is evaluated by national and international external reviewers and presented to the Teaching Board. After approval, the theses are defended in the final exam before a commission appointed by the Rector of the University.
