Fractional Chern insulators in alternating twisted multilayer MoTe
Xi-Hang Feng, Shi-Ping Ding, Xiang-Jian Hou +2
The paper investigates how sliding and electric-field tuning of alternating twisted trilayer and tetralayer MoTe₂ can create topological hole bands with tunable quantum geometry, a…
Theory of Integer Quantum Hall Effect in Irrational Magnetic Field
Zhao-Wen Miao, Chen Zhao, Jin-Hua Gao +1
The conventional theory of the integer quantum Hall effect (IQHE) fails for irrational magnetic fields owing to the breakdown of magnetic translational symmetry. Here, based on the…
Theory of Correlated Hofstadter Spectrum in Magic-Angle Graphene
Chen Zhao, Zhaowen Miao, Zhen Ma +4
The magnetic-field-induced correlated Chern insulator (CCI) states in magic-angle twisted bilayer graphene (MATBG) have been intensively studied in experiments, but a simple and cl…
Sliding-tuned Quantum Geometry in Moiré Systems: Nonlinear Hall Effect and Quantum Metric Control
Shi-Ping Ding, Miao Liang, Tian-Le Wu +4
Sliding is a ubiquitous phenomenon in moiré systems, but its direct influence on moiré bands, especially in multi-twist moiré systems, has been largely overlooked to date. Here,…
Theory of Localized States in Quasiperiodic Lattices
Jin-Rong Chen, Xin-Yu Guo, Shi-Ping Ding +4
The physics of localized states in quasiperiodic lattices has been extensively studied for decades, but still lacks an comprehensive theoretical framework. Recently, we developed a…
Cavity QED based on strongly localized modes: exponentially enhancing single-atom cooperativity
Qian Bin, Ying Wu, Jin-Hua Gao +3
Large single-atom cooperativity in quantum systems is important for quantum information processing. Here, we propose to exponentially enhance the single-atom cooperativity paramete…
