Field-Tunable Valley Coupling and Localization in a Dodecagonal Semiconductor Quasicrystal
Zhida Liu, Qiang Gao, Yanxing Li +11
Quasicrystals are characterized by atomic arrangements possessing long-range order without periodicity. Van der Waals (vdW) bilayers provide a unique opportunity to controllably va…
Nonlocal Moments in the Chern Bands of Twisted Bilayer Graphene
Patrick J. Ledwith, Junkai Dong, Ashvin Vishwanath +1
Twisted bilayer graphene (TBG) has elements in common with two paradigmatic examples of strongly correlated physics: quantum Hall physics and Hubbard physics. On one hand, TBG host…
Constraints on real space representations of Chern bands
Qingchen Li, Junkai Dong, Patrick J. Ledwith +1
A Chern band is characterized by a Wannier obstruction indicating the absence of a basis of complete, orthogonal, and exponentially-localized states. Here, we study the properties…
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…
Strong interactions and isospin symmetry breaking in a supermoiré lattice
Yonglong Xie, Andrew T. Pierce, Jeong Min Park +10
In multilayer moiré heterostructures, the interference of multiple twist angles ubiquitously leads to tunable ultra-long-wavelength patterns known as supermoiré lattices. However,…
Higher vortexability: zero field realization of higher Landau levels
Manato Fujimoto, Daniel E. Parker, Junkai Dong +3
The rise of moiré materials has led to experimental realizations of integer and fractional Chern insulators in small or vanishing magnetic fields. At the same time, a set of minima…
