Workshop on Topology in Magnetic Materials

Herzberg 193 5025 Asp Switzerland
Jonathan White (Laboratory for Neutron Scattering, Paul Scherrer Institut), Motoaki Hirayama, Naoya Kanazawa, Oksana Zaharko (PSI - Paul Scherrer Institut), Romain Sibille (PSI - Paul Scherrer Institut)

The main goal of the workshop is to bring together experts in the fields of magnetism and topology in order to discuss the accomplished progress and perspectives for future developments in the field of bulk magnetic topological materials. The program will cover fundamental aspects such as symmetry in topology, focus on topological and emergent properties of non-collinear magnets and multi-k spin textures as well as related experimental and theoretical methods. While a broad overview of the field will be discussed, a particular emphasis will be on the application of scattering techniques for the experimental elucidation of complex magnetic phases and textures. We aim to develop interdisciplinary communication and collaborations among internationally leading experts and to encourage young researchers to contribute to the field.
