$ab$ - $ini t i o$ Approaches for Low-Energy Spin Hamiltonians

Kira Riedl, Ying Li, Roser Valenti +1

Implicit in the study of magnetic materials is the concept of spin Hamiltonians, which emerge as the low-energy theories of correlation-driven insulators. In order to predict and e…

Signatures of a gearwheel quantum spin liquid in a spin- $\frac{1}{2}$ pyrochlore molybdate Heisenberg antiferromagnet

Yasir Iqbal, Tobias Müller, Kira Riedl +6

We theoretically investigate the low-temperature phase of the recently synthesized Lu $_{2}$ Mo $_{2}$ O $_{5}$ N $_{2}$ material, an extraordinarily rare realization of a $S = 1/2$ three-dimension…

Ab initio determination of spin Hamiltonians with anisotropic exchange interactions: the case of the pyrochlore ferromagnet Lu $_{2}$ V $_{2}$ O $_{7}$

Kira Riedl, Daniel Guterding, Harald O. Jeschke +2

We present a general framework for deriving effective spin Hamiltonians of correlated magnetic systems based on a combination of relativistic ab initio density functional theory ca…
