Moir\'{e} optical phonons dancing with heavy electrons in magic-angle twisted bilayer graphene

H Shi, W Miao, X Dai - arxiv preprint arxiv:2402.11824, 2024 - arxiv.org
Electron-phonon coupling in magic-angle twisted bilayer graphene is an important but
difficult topic. We propose a scheme to simplify and understand this problem. Weighted by …
