Topology and Frustration

We carry out neutron scattering studies of novel magnetic orders and exotic excitations in quantum materials, with a particular interest in exploring the emergent quantum phenomena that arise from topology and frustration in correlated electron systems. We are also engaged in the single-crystal growth of quantum materials, and have a strong interest and competence in the development and application of the polarized neutron scattering techniques.
