Scientific Calendar Event



Description An ICTP Hybrid Meeting

This 5-day school consists of lectures and hands-on sessions on a wide range of electronic-structure methods based on Wannier functions. The event targets graduate students, early-career scientists and experienced users.

Wannier functions (WFs) are used to understand the nature of chemical bonding, calculate topological and geometrical quantities, efficiently interpolate band-structure properties and more. This event includes highlight talks that provide a historical and broad perspective on WFs in electronic structure, dedicated lectures to the theory and methods of WFs, as well as hands-on tutorials at the basic and advanced level. The school is designed to allow participants to join both in-person and online, and covers a wide range of complex materials properties using the software packages listed below.

Topics
  • Maximally-localized Wannier functions (Wannier90)
  • Advanced Wannier functions methods: symmetry-adapted, SCDM, transport (Wannier90)
  • Partly occupied Wannier functions (ASE)
  • Tight-binding models (PythTB)
  • Topological properties (Z2pack & WannierTools)
  • Berry-phase properties (WannierBerri)
  • Automated wannierisation (AiiDA)
  • Electron-phonon coupling (EPW)
  • Dynamical mean-field theory (TRIQS)

Grants: A limited number of grants are available to support the attendance of selected participants, with priority given to participants from developing countries. There is no registration fee.

The School will be followed the week after (23 - 27 May 2022) by the Wannier 2022 Developers Meeting (smr 3757), devoted to foster integration between several packages composing the Wannier software ecosystem.
