Organising Committee

Scope

This workshop brings together physicists and mathematicians working on systems and phenomena influenced by topological structures. Possible topics include magnetic materials, ferroelectrics, structured light, superfluids, superconductors, and liquid crystals. It is open to all Action participants, researchers who plan to join the Action, and researchers who may benefit from the expertise within the network.

The program will feature experimental, theoretical, numerical, and mathematical presentations and discussions, alongside invited talks by leading researchers and a poster session. In addition, a Management Committee Meeting and a Core Group Meeting will be held during the workshop.
