Realization of the Haldane Chern insulator in a moiré lattice

Kavli Affiliate: Jie Shan | First 5 Authors: Wenjin Zhao, Kaifei Kang, Lizhong Li, Charles Tschirhart, Evgeny Redekop | Summary: The Chern insulator displays a quantized Hall effect without Landau levels. In a landmark paper in 1988, Haldane showed that a Chern insulator could be realized through complex next-nearest-neighbor hopping in a honeycomb lattice. Despite […]

Viscosity Metamaterials

Kavli Affiliate: Itai Cohen | First 5 Authors: Prateek Sehgal, Meera Ramaswamy, Edward Y. X. Ong, Christopher Ness, Itai Cohen | Summary: Metamaterials are composite structures whose properties arise from a mesoscale organization of their constituents. Provided this organization occurs on scales smaller than the characteristic lengths associated with their response, it is often possible […]
