A Chiral Superlattice Route to Spin-Split Topological Antiferromagnetism
Thao Dinh, Mengke Liu, Jian-Xiang Qiu +48
The interplay between chirality and magnetism is a profound topic, spanning particle physics, condensed matter, chemistry and origin of life. In this paper, we study this interplay…
Non-uniform quantum geometry stabilizes generalized Wigner crystals
Nicolás Morales-Durán, Tobias M. R. Wolf, Jingtian Shi +3
Moiré materials host fractional Chern insulators and electron crystals in close proximity, but the mechanism selecting between them remains an open question. We address this compet…
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…
Band mixing and particle-hole asymmetry in moiré fractional Chern insulators
Nicolás Morales-Durán, Jingtian Shi, Cristian Voinea +2
We investigate the effect of remote band mixing on the stability of fractional Chern insulators in a family of models that approximate continuum descriptions of moiré materials. Ou…
