Topology and compact molecular orbitals in twisted bilayer WSe
Chenyuan Li, Rwik Dutta, Fang Xie +4
Recent observations of superconductivity in twisted bilayer WSe (tWSe) have motivated theoretical proposals for unconventional pairing mechanisms. A central question is whe…
High-throughput discovery of moiré homobilayers guided by topology and energetics
Naoto Nakatsuji, Jennifer Cano, Valentin Crépel
Van der Waals heterostructures promise on-demand designer quantum phases through control of monolayer composition, stacking, twist angle, and external fields. Yet, experimental eff…
Two-dimensional helical superconductivity and gapless superconducting edge modes in the 1T-WS/2H-WS heterophase bilayer
Xuance Jiang, Jennifer Cano, Yuan Ping +2
We propose a material platform comprised of transition metal dichalcogenide (TMDC) heterostructures to realize the two-dimensional (2D) helical superconductivity with an intrinsic…
Effects of Berry curvature on ideal fractional Chern insulator many-body gaps
Jingtian Shi, Jennifer Cano, Nicolás Morales-Durán
We investigate the many-body ground states in a family of fractionally-filled bands where the Berry curvature fluctuations can be tuned while maintaining ideal quantum geometry. We…
Topological chiral superconductivity from antiferromagnetic correlations in moiré bands with extreme spin-orbit coupling
Chenyuan Li, Fang Xie, Jennifer Cano +1
Motivated by the strong-correlation phenomenology observed near the superconducting phase in twisted bilayer WSe, we study multi-orbital - models that are derived from di…
Kondo-lattice phenomenology of twisted bilayer WSe from compact molecular orbitals of topological bands
Fang Xie, Chenyuan Li, Jennifer Cano +1
The discovery of superconductivity and correlated electronic phases in twisted bilayer WSe (Xia et al., Nature 2024; Guo et al., Nature 2025) has generated considerable excitem…
