Strategy to extract Kitaev interaction using symmetry in honeycomb Mott insulators

Abstract

The Kitaev model describes bond dependent interactions on a 2D honeycomb lattice and is often associated with experiments to realise a quantum spin liquid state; however, despite many potential candidates, data on such materials are complex to interpret. Here, the authors propose a method to extract and separate exchange parameters in Kitaev materials, which can be applied to techniques such as inelastic neutron scattering and angle-dependent ferromagnetic resonance.
