Hundness in twisted bilayer graphene: correlated gaps and pairing
Seongyeon Youn, Beomjoon Goh, Geng-Dong Zhou +2
We characterize gap-opening mechanisms in the topological heavy fermion (THF) model of magic-angle twisted bilayer graphene (MATBG), with and without electron-phonon coupling, usin…
Electron phonon coupling in the topological heavy fermion model of twisted bilayer graphene
Yi-Jie Wang, Geng-Dong Zhou, Biao Lian +1
On flat bands of the magic-angle twisted bilayer graphene, exotic correlation physics unfolds. Phonons, through mediating an effective electron-electron interaction, can play a cru…
Correlated Charge Density Wave Insulators in Chirally Twisted Triple Bilayer Graphene
Wenxuan Wang, Gengdong Zhou, Wenlu Lin +16
Electrons residing in flat-band system can play a vital role in triggering spectacular phenomenology due to relatively large interactions and spontaneous breaking of different dege…
Correlated insulators and charge density wave states in chirally twisted triple bilayer graphene
Geng-Dong Zhou, Yi-Jie Wang, Wen-Xuan Wang +2
Motivated by recent experimental observations of displacement-field-tuned correlated insulators at integer and half-integer fillings in chirally twisted triple bilayer graphene (CT…
Molecular Pairing in Twisted Bilayer Graphene Superconductivity
Yi-Jie Wang, Geng-Dong Zhou, Shi-Yu Peng +2
We propose a theory for how the weak phonon-mediated interaction (meV) wins over the prohibitive Coulomb repulsion (meV) and leads to…
