Chiral superconductors and competing states across a Lifshitz transition in rhombohedral pentalayer graphene
Chuanqi Zheng, Cheng Xu, Chushan Li +19
Rhombohedral multilayer graphene hosts a distinctive low-energy electronic structure in which strong Coulomb interactions and nontrivial quantum geometry intertwine to generate exo…
Visualizing flat-band spatial renormalization in rhombohedral graphene superlattices
Peng-Cheng Pan, Shihao Zhang, Yang Zhang +10
Rhombohedral graphene/hBN moiré superlattices exhibit flat-band-driven emergent phases, including superconductivity and the fractional quantum anomalous Hall effect (FQAHE), yet th…
A fractional quantum Hall factory on quantum processors: constant-depth preparation of clustered non-Abelian states
Cheng Xu, Ching Hua Lee, Hong-Hao Tu +1
Non-Abelian anyons arise as exotic excitations in fractional quantum Hall (FQH) matter and have proved very elusive to realize in conventional platforms. In this work, we show that…
Interference-Enhanced Large Electron-Phonon Coupling from Raman-active Breathing Modes in Moiré Semiconductors
Ning Mao, Shaozheng Wang, Cheng Xu +6
Superconductivity was recently observed in twisted WSe2 and MoTe2, raising a central question: is the pairing driven by electronic correlations, by phonons, or by both? Answering i…
Kohn--Luttinger Superconductivity in Flat Chern Bands
Nianlong Zou, Cheng Xu, Yafis Barlas +1
Recent observations of superconductivity near correlated topological phases in flat bands suggest a facile link between flat-band geometry and electron pairing. In this work, we re…
Breaking the Trade-off: Bulk 2D Ising Superconductivity with High Tc and Giant Interlayer Spacing via a Unique Chain Intercalation in (BaS)1/3TaS2
Ziyi Zhu, Leiming Chen, Xiangqi Liu +11
Two-dimensional (2D) transition metal dichalcogenides (TMDs) are promising platforms for low dimensional superconductivity. However, in conventional intercalated systems, achieving…
