Hidden multipolar orders of dipole-octupole doublets on a triangular lattice
Hidden multipolar orders of dipole-octupole doublets on a triangular lattice
Motivated by the recent development in strong spin-orbit-coupled materials, we consider the dipole-octupole doublets on the triangular lattice. We propose the most general interaction between these unusual local moments. Due to the spin-orbit entanglement and the special form of its wavefunction, the dipole-octupole doublet has a rather peculiar property under …
