Dive into a comprehensive hands-on tutorial focused on first-principles calculation of Hubbard parameters, part of the Advanced Quantum ESPRESSO series. Explore topics such as chromium oxide, band structure analysis, occupancy matrices, and the practical implementation of Hubbard parameters. Examine the role of symmetry in calculations and learn how to perform ground state and band structure calculations using Density Functional Theory (DFT). Engage with exercises and questions throughout the tutorial to reinforce your understanding of concepts like MNCF bands and the application of Hubbard parameters in real-world scenarios. Gain valuable insights into advanced quantum mechanics and materials science over the course of this nearly two-hour session.
