Exchange interactions, Jahn-Teller coupling, and multipole orders in pseudospin one-half 5d^{2} Mott insulators
We develop a microscopic theory of multipole interactions and orderings in 5d^{2} transition metal ion compounds. In a cubic environment, the ground state of 5d^{2} ions is a non-Kramers E_{g} doublet, which is nonmagnetic but hosts quadrupole and octupole moments. We derive low-energy pseudospin on...
