Imaging moiré flat bands in 3D reconstructed WSe2/WS2 superlattices

Kavli Affiliate: Michael F. Crommie | First 5 Authors: Hongyuan Li, Shaowei Li, Mit H. Naik, Jingxu Xie, Xinyu Li | Summary: Moir’e superlattices in transition metal dichalcogenide (TMD) heterostructures can host novel correlated quantum phenomena due to the interplay of narrow moir’e flat bands and strong, long-range Coulomb interactions1-5. However, microscopic knowledge of the […]

Physics Successfully Implements Lagrange Multiplier Optimization

Kavli Affiliate: Eli Yablonovitch | Summary:Optimization is a major part of human effort. While being mathematical, optimization is also built into physics. For example, physics has the principle of Least Action, the principle of Minimum Entropy Generation, and the Variational Principle. Physics also has physical annealing which, of course, preceded computational Simulated Annealing. Physics has […]
