Description
A recurring theme in contemporary quantum materials physics is the understanding of new quantum magnets which display novel disordered ground states due to geometric frustration, quantum fluctuations or both. Neutron scattering, arguably the most powerful probe of magnetism in solids, has a proud Canadian history. Modern neutron sources and instrumentation have given us unprecedented capabilities to study weaker, more diffuse signals in new quantum materials. I will review how these developments came to be, and how modern neutron techniques are well suited for my group’s focus: elucidating quantum disordered ground states and their exotic excitations in new materials.
