Spin point group symmetry and classification of non-relativistic spin splitting in non-collinear magnetic structures: identification of high-order spin splitting types (ℓ = 5, 7 and 9)

A comprehensive classification of coplanar and non-coplanar spin point groups, with and without time-reversal symmetry, is presented together with an analysis of the symmetry-allowed spin splitting of electronic bands. New spin textures with leading orders ℓ = 5, 7 and 9 are identified, and LaMnAu5 is proposed as a real material exhibiting ℓ = 5 spin splitting.

Learning lattice parameters from powder X-ray diffraction data using invariants

We introduce a smooth, invariant representation of the reciprocal lattice that avoids the discontinuities of unit-cell parameterizations, and show it improves machine-learned lattice parameter prediction from powder X-ray diffraction data.
