Theory of Moire Magnets and Topological Magnons: Applications to Twisted Bilayer CrI3
Kyoung-Min Kim, Do Hoon Kiem, Grigory Bednik +2
We develop a comprehensive theory of twisted bilayer magnetism. Starting from the first-principles calculations of two-dimensional honeycomb magnet CrI3, we construct the generic s…
Replica Higher-Order Topology of Hofstadter Butterflies in Twisted Bilayer Graphene
Sun-Woo Kim, Sunam Jeon, Moon Jip Park +1
The Hofstadter energy spectrum of twisted bilayer graphene is found to have recursive higher-order topological properties. We demonstrate that higher-order topological insulator (H…
Bloch theorem dictated wave chaos in microcavity crystals
Chang-Hwan Yi, Hee Chul Park, Moon Jip Park
Universality class of wave chaos emerges in many areas of science, such as molecular dynamics, optics, and network theory. In this work, we generalize the wave chaos theory to cavi…
