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…
Spontaneous Twirls and Structural Frustration in Moiré Materials
Jingtian Shi, Gaurav Chaudhary, Allan H. MacDonald +1
Structural twirls form spontaneously in the domain wall networks of some moiré materials. We show that in heterobilayers, neighboring twirl chiralities tend to anti-align, forming…
Effects of Berry curvature on ideal fractional Chern insulator many-body gaps
Jingtian Shi, Jennifer Cano, Nicolás Morales-Durán
We investigate the many-body ground states in a family of fractionally-filled bands where the Berry curvature fluctuations can be tuned while maintaining ideal quantum geometry. We…
Adiabatic Approximation and Aharonov-Casher Bands in Twisted Homobilayer TMDs
Jingtian Shi, Nicolás Morales-Durán, Eslam Khalaf +1
Topological flat moiré bands with nearly ideal quantum geometry have been identified in homobilayer transition metal dichalcogenide moiré superlattices, and are thought to be cruci…
Magic Angles and Fractional Chern Insulators in Twisted Homobilayer TMDs
Nicolás Morales-Durán, Nemin Wei, Jingtian Shi +1
We explain the appearance of magic angles and fractional Chern insulators in twisted K-valley homobilayer transition metal dichalcogenides by mapping their continuum model to a Lan…
