Magnetism is a centerpiece of modern condensed matter physics and arises from strong electronic correlations in materials. In recent years, a plethora of topological phenomena has been discovered in condensed matter systems, shedding new light on the study of magnetism in strongly correlated materials. The motivation of the workshop “Topology and Fractionalization in Magnetic Materials” is to bring the experts together to discuss the most exciting new progress in the field of quantum magnetism, with emphasis on the aspects of topology and fractionalization. 

This 6-day workshop will take place at the Physics Department of The Ohio State University, during May 15-20, 2023. It will consist of a one-day tutorial session (May 15) and a five-day conference (May 16-20). 

Synthesis of new materials and new experimental probes are the keys to unveil new exotic phenomena. We have invited a strong group of chemists, physicists, and material scientists to discuss the newest developments in the frontier of magnetic materials. Experts on a range of experimental probes for magnetic excitations, including neutron scattering spectroscopy, optical spectroscopy, thermal, charge and spin transport, are invited to discuss the exciting new advances in study of magnetic materials. 

Topological excitations in magnetic materials is a new emerging field, where many theoretical predictions, including a recent symmetry-based material search effort, await material realizations and experimental confirmations. We have invited theorists and experimentalists with expertise in this field to discuss recent progress in studying Hermitian and non-Hermitian topological magnons, and topological semimetals. 

Frustrated magnetism is another main topic of this workshop, with a focus on quantum spin liquids and fractionalization. Combined efforts of new material discovery, experimental characterization and theoretical investigation have been instrumental for the identification and confirmation of quantum spin liquids and fractionalized excitations therein. We have invited experts with these different expertises to discuss timely advances in this fascinating yet challenging field. 

We expect the workshop to achieve the following goals. First, the tutorial session will provide a timely review of literature and introductory education for young researchers entering this field. Second, the conference will provide an ideal platform for experts in the field to exchange their results, to generate new ideas and to initiate new collaborations. Finally, the gathering of many researchers with different expertise will allow us to examine the problems from a wide range of angles, to identify the main challenges, and to work out the solutions.
