The 2026 Wannier90 Developer Meeting was held 7–11 September 2026 at the Scuola Internazionale Superiore di Studi Avanzati (SISSA) in Trieste, Italy.
The meeting brought together the developers of Wannier90 and of the codes that make up the wider Wannier ecosystem. It came shortly after the release of v4.0, the first version to provide an MPI-parallel library interface, and was dedicated to coordinating development across projects, sharing capabilities and drawing a roadmap for future work. Alongside invited and contributed talks, much of the week was given over to discussion and to concentrated team-oriented programming.
Organisers: Antimo Marrazzo (SISSA), Jerome Jackson (STFC Daresbury Laboratory), Jae-Mo Lihm (Flatiron Institute), Nataliya Paulish (PSI), Giovanni Pizzi (PSI), Junfeng Qiao (EPFL/PSI).
