Moiré-induced altermagnetism from nonmagnetic constituents
Jingtian Shi, Maxim Khodas, Ivar Martin
We propose a mechanism for nonmagnetic materials to develop altermagnetic order by moiré interference with nonmagnetic substrate, which is driven by structural relaxation and spont…

Symmetry-protected cubic-touching topological surface bands with tunable singularities
Jingtian Shi, Taylor L. Hughes, Ivar Martin
We propose a class of topological surface bands in three-dimensional topological crystalline insulators that have symmetry-protected cubic-order band touching. Within the symmetry…
