Tunable Multiband Geometry and Fractional Phases in Higher Vortexable Systems
Xiaohan Wan, Siddhartha Sarkar, Ting Cao +3
Higher vortexability is often viewed as a route to topological flat bands with higher-Landau-level-like quantum geometry. Here we emphasize a complementary perspective: it provides…
Topological Charge-Transfer Excitons
Huiyuan Zheng, Kaijie Yang, Ting Cao +1
Excitons possess internal structure absent from single-particle Bloch particles, allowing their band topology to emerge from the bound-state structure rather than being inherited f…
Electrically Programmable Correlated Topology and Magnetism in a Moiré Trilayer
Christiano Wang Beach, Courtney Baier, Kaijie Yang +15
Strong electron-electron interactions underlie a wide range of quantum many-body phenomena, including magnetism, superconductivity, and charge fractionalization. A central goal is…
Switching Chern number by sliding and gating in alternately twisted tetralayer MoTe2
Xiao-Wei Zhang, Kaijie Yang, Xiaodong Xu +2
Switching the bulk Chern number in topological materials is of central importance for the design of topological electronic devices. Motivated by recent observations of integer and…
Ward identities and orbital magnetization in current density functional theory
Giovanni Vignale, Junren Shi, Di Xiao +1
We revisit the derivation of the orbital magnetization formula for periodic crystals in current density functional theory (CDFT)[1]. Our new derivation computes the linear response…
Orbital Magnetization of Correlated States in Twisted Bilayer Transition Metal Dichalcogenides
Xiaoyu Liu, Chong Wang, Haoran Chen +3
Recent observations of quantum anomalous Hall effects in moiré systems have revealed the emergence of interaction-driven ferromagnetism with significant orbital contributions. To…
