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. O…
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…
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…
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 cru…
