Hidden spin-orbital hexagonal ordering induced by strong correlations in LiVS$_2$

Abstract

We present a first-principles many-body analysis of multi-orbital lattice susceptibilities in the metallic phase of the quasi-twodimensional compound LiVS2_2. We base this on advanced correlated electronic structure methods for the t2gt_{2g}-shell to reveal a highly entangled spin-orbital hexagonal ordering (SOHO) bringing about an inherently intersite order parameter for the trimerization transition, which eventually leads to an intriguing insulating phase at low temperature.
