[QE-users] Advanced Quantum ESPRESSO tutorial: Hubbard and Koopmans functionals from linear response

[Iurii TIMROV]

Dear Quantum ESPRESSO community,


We are pleased to announce  the "Advanced Quantum ESPRESSO tutorial: Hubbard and Koopmans functionals from linear response".


Dates: 9-11 November 2022

Format: Online

Registration fee: 0 (free of charge)

Deadline for applications: 1 October 2022

Website of the event: https://sites.google.com/view/hubbard-koopmans


The goal of this tutorial is to introduce PhD students, postdocs, and junior scientists to the use of advanced functionals aimed at modeling complex materials, such as the extended Hubbard and Koopmans functionals. By eliminating self-interaction errors and restoring total energy piecewise linearity, these advances broaden the scope of DFT by either improving the ground-state description of transition-metal and rare-earth compounds or by giving access to accurate spectral properties (like fundamental band gaps and band structures). Their actual implementation also takes advantage of linear-response theory through the self-consistent incarnation contained in density-functional perturbation theory. The first day of the tutorial will be devoted to an introduction to fundamental aspects of DFT using local and semi-local functionals, its application to materials science and physics, and its limitations. In the next 2 days, the tutorial will cover the theoretical framework of Hubbard and Koopmans functionals (the main topic of this event) and their applications to representative case studies. The reference computational platform of the tutorial will be Quantum ESPRESSO, a widely used open-source electronic-structure software, which implements both extended Hubbard and Koopmans functionals.


If attending the Psi-k conference in Lausanne, feel free to come and see us at the MARVEL and MaX booths to learn more about the virtual tutorial and the codes involved.
