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…
Ferromagnetism and Topology of the Higher Flat Band in a Fractional Chern Insulator
Heonjoon Park, Jiaqi Cai, Eric Anderson +18
The recent observation of the fractional quantum anomalous Hall effect in moiré fractional Chern insulators provides an opportunity to investigate zero magnetic field anyons. To po…
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…
Continuously tunable uniaxial strain control of van der Waals heterostructure devices
Zhaoyu Liu, Xuetao Ma, John Cenker +13
Uniaxial strain has been widely used as a powerful tool for investigating and controlling the properties of quantum materials. However, existing strain techniques have so far mostl…
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…
Absence of Weyl nodes in EuCdAs revealed by the carrier density dependence of the anomalous Hall effect
Yue Shi, Zhaoyu Liu, Logan A. Burnett +8
The antiferromagnetic layered compound EuCdAs is widely considered as a leading candidate of ideal Weyl semimetal, featuring a single pair of Weyl nodes in its field-induce…
