Frustrated and topological magnets

Frustrated and topological quantum materials have become a focus of intense research owing to the remarkable possibilities to realize emergent quasiparticles that do not correspond to any theoretically known elementary particles, such as magnetic monopoles and Majorana fermions. Realization and eventual manipulation of those exotic quasiparticles in condensed matter can lead to potential applications for future information technology such as decoherence-free quantum computing architecture.
