On the origin of anomalous hysteresis in graphite/boron nitride transistors
Dacen Waters, Derek Waleffe, Ellis Thompson +9
Field-effect devices constructed by stacking flakes of van der Waals (vdW) materials, with hexagonal boron nitride (hBN) playing the role of gate dielectric, often exhibit virtuall…
Interplay of electronic crystals with integer and fractional Chern insulators in moiré pentalayer graphene
Dacen Waters, Anna Okounkova, Ruiheng Su +8
The rapid development of moiré quantum matter has recently led to the remarkable discovery of the fractional quantum anomalous Hall effect, and sparked predictions of other novel c…
Strongly interacting Hofstadter states in magic-angle twisted bilayer graphene
Minhao He, Xiaoyu Wang, Jiaqi Cai +8
Magic-angle twisted bilayer graphene (MATBG) hosts a multitude of strongly correlated states at partial fillings of its flat bands. In a magnetic field, these flat bands further ev…
Time-Domain Signatures of Distinct Correlated Insulators in a Moiré Superlattice
Eric A. Arsenault, Yiliu Li, Birui Yang +6
Among expanding discoveries of quantum phases in moiré superlattices, correlated insulators stand out as both the most stable and most commonly observed. Despite the central import…
Visualizing the microscopic origins of topology in twisted molybdenum ditelluride
Ellis Thompson, Keng Tou Chu, Florie Mesple +14
In moiré materials with flat electronic bands and suitable quantum geometry, strong correlations can give rise to novel topological states of matter. The nontrivial band topology o…
Direct magnetic imaging of fractional Chern insulators in twisted MoTe with a superconducting sensor
Evgeny Redekop, Canxun Zhang, Heonjoon Park +10
In the absence of time reversal symmetry, orbital magnetization provides a sensitive probe of topology and interactions, with particularly rich phenomenology in Chern insulators wh…
Topological flat bands in a family of multilayer graphene moiré lattices
Dacen Waters, Ruiheng Su, Ellis Thompson +10
Moiré materials host a wealth of intertwined correlated and topological states of matter, all arising from flat electronic bands with nontrivial quantum geometry. A prominent examp…
Local probe of bulk and edge states in a fractional Chern insulator
Zhurun Ji, Heonjoon Park, Mark E. Barber +6
Fractional quantum Hall effect (FQHE) is a prime example of topological quantum many-body phenomena, arising from the interplay between strong electron correlation, topological ord…
Coherent Modulation of Two-Dimensional Moiré States with On-Chip THz Waves
Yiliu Li, Eric A. Arsenault, Birui Yang +11
Van der Waals (vdW) structures of two-dimensional materials host a broad range of physical phenomena. New opportunities arise if different functional layers may be remotely modulat…
