Phase diagram of the J_{1}-J_{2} Heisenberg second-order topological quantum magnet

Competing interactions in quantum magnets lead to a variety of emergent states, including ordered phases, nematic magnets, and quantum spin liquids. Among them, topological quantum magnets represent a promising platform to create topological excitations protected by the bulk many-body excitation gap...
