2020 Subaru Forester Review: The Safety-First, Can’t-Go-Wrong-Buying-One Compact SUV

Scientists in the University of Hong Kong and Hunan Normal University showed that, in homobilayer transition metal dichalcogenides, the real-space Berry phase from moiré patterns manifests as a periodic magnetic field. The field magnitude can reach hundreds of Tesla for a typical moiré period of 10 nanometers. For low energy carriers, this Berry phase induced magnetic field realizes a topological
