Uncovering Political Promotion in China: A Network Analysis of Patronage Relationship in Autocracy
Zhengxuan Wu, Jason Luo, Xiyu Zhang
Understanding patronage networks in Chinese Bureaucracy helps us quantify the promotion mechanism underlying autocratic political systems. Although there are qualitative studies an…
Correlated Insulator Behaviour at Half-Filling in Magic Angle Graphene Superlattices
Yuan Cao, Valla Fatemi, Ahmet Demir +9
Van der Waals (vdW) heterostructures are an emergent class of metamaterials comprised of vertically stacked two-dimensional (2D) building blocks, which provide us with a vast tool…
Superlattice-induced insulating states and valley-protected orbits in twisted bilayer graphene
Y. Cao, J. Y. Luo, V. Fatemi +6
Twisted bilayer graphene (TwBLG) is one of the simplest van der Waals heterostructures, yet it yields a complex electronic system with intricate interplay between moiré physics and…
Observation of Helical Edge States and Fractional Quantum Hall Effect in a Graphene Electron-hole Bilayer
J. D. Sanchez-Yamagishi, J. Y. Luo, A. F. Young +5
A quantum Hall edge state provides a rich foundation to study electrons in 1-dimension (1d) but is limited to chiral propagation along a single direction. Here, we demonstrate a ve…
