Abstract: In this report, we propose a new concept of one-dimensional (1D) closed lines of Dirac magnon nodes in two-dimensional (2D) momentum space of quasi-2D quantum magnetic systems. They are termed “2D Dirac magnon nodal-line loops”.… read more here.

Abstract: Using both an effective three-band model and ab initio calculations, we have investigated various topological features in the cubic ferromagnetic $5{d}^{1,2}$ systems showing large spin-orbit coupling (SOC): ${\mathrm{Ba}}_{2}{\mathrm{NaOsO}}_{6}, {\mathrm{Sr}}_{2}{\mathrm{SrOsO}}_{6}$, and ${\mathrm{Ba}}_{2}B{\mathrm{ReO}}_{6}$ ($B$=Mg, Zn). In the… read more here.
