Joint ICTP MARVEL College: Materials Simulations in the age of AI
In June 2026, Dr. Iurii Timrov contributed to the organization of and lectured at the "Joint ICTP–MARVEL College: Materials Simulations in the Age of AI", held at the Abdus Salam International Centre for Theoretical Physics (ICTP) in Trieste, Italy. The two-week international school brought together graduate students and early-career researchers for intensive training in state-of-the-art computational materials science, combining lectures with practical hands-on sessions using open-source electronic-structure and atomistic simulation codes. The program covered a broad range of topics, including density-functional theory (DFT), density-functional perturbation theory (DFPT), many-body perturbation theory (GW and BSE), Wannier functions, advanced electronic-structure methods, molecular dynamics, enhanced sampling techniques, and modern machine-learning approaches for materials simulations. Dr. Timrov, together with Prof. Matteo Cococcioni, delivered lectures and a hands-on tutorial on DFT+U and DFT+U+V methods, focusing on the first-principles calculation of Hubbard U and inter-site V parameters using linear response theory and its reformulation within density-functional perturbation theory (DFPT). The session introduced the theoretical foundations of these methods and demonstrated their practical implementation in the Quantum ESPRESSO package. A video recording of the lecture is available here.
