  • In chiral helimagnets, the Dzyaloshinskii–Moriya interaction is known to stabilize skyrmions, but the microscopic roots remain enigmatic. Here, Janson et al. apply a multi-scale approach to Cu2OSeO3and show that its skyrmions can be traced back to magnetic tetrahedra of a quantum nature.

  • Honeycomb iridates are candidates for the realization of a Kitaev spin liquid, displaying properties such as the protection of quantum information. Here, the authors investigate the phase diagram of honeycomb Li2IrO3, using quantum chemistry methods to derive the relevant effective spin Hamiltonian.

  • Strongly correlated quantum spin liquid phases form when quantum fluctuations prevent magnetic ordering, which normally requires low spin systems that cannot be analyzed semiclassically. Here, the authors show that a large-spin Kitaev model supports a spin liquid phase in the semiclassical limit.
