Iberian-German WE-Heraeus Seminar 2026

Topological Matter:

10 Years After the Nobel Prize

March 29 – April 2, 2026

March 29 – April 2, 2026

The Iberian-German WE-Heraeus Seminar 2026 will convene leading scientists and emerging researchers in topological matter to mark the 10th anniversary of the 2016 Nobel Prize in Physics. The prize recognised groundbreaking theoretical discoveries of topological phase transitions and topological phases of matter, with one half awarded to David J. Thouless and the other half jointly to F. Duncan M. Haldane and J. Michael Kosterlitz. The event will explore the frontier of this transformative research area, emphasising its significance for future technologies in quantum computing, spintronics and energy-efficient devices.

This seminar is organised under the prestigious auspices of the Wilhelm and Else Heraeus Foundation, a major supporter of scientific advancement in the natural sciences.
