Abstract: We show how an accurate first-principles treatment of the canted-anti-ferromagnetic ground state of ${\mathrm{Sr}}_{2}{\mathrm{IrO}}_{4}$, a prototypical $5d$ correlated spin-orbit coupled material, can be obtained without invoking any free parameters, such as the Hubbard $U$ or… read more here.

Abstract: In this paper, we present a method for calculation of spin groups elements for known pseudo-orthogonal group elements with respect to the corresponding two-sheeted coverings. We present our results using the Clifford algebra formalism in… read more here.
