Van der Waals Heterostructure Polaritons with moiré-Induced Nonlinearity
Long Zhang, Fengcheng Wu, Shaocong Hou +6
Controlling matter-light interactions with cavities is of fundamental importance in modern science and technology. It is exemplified in the strong-coupling regime, where matter-lig…
Acoustic-phonon-mediated superconductivity in rhombohedral trilayer graphene
Yang-Zhi Chou, Fengcheng Wu, Jay D. Sau +1
Motivated by the observation of two distinct superconducting phases in the moiréless ABC-stacked rhombohedral trilayer graphene, we investigate the electron-acoustic-phonon couplin…
Charge density wave and finite-temperature transport in minimally twisted bilayer graphene
Yang-Zhi Chou, Fengcheng Wu, Jay D. Sau
We study phenomena driven by electron-electron interactions in the minimally twisted bilayer graphene (mTBLG) with a perpendicular electric field. The low-energy degrees of freedom…
Quantum Phase Diagram of a Moiré-Hubbard Model
Haining Pan, Fengcheng Wu, Sankar Das Sarma
We theoretically study a generalized Hubbard model on moiré superlattices of twisted bilayers, and find very rich filling-factor-dependent quantum phase diagrams tuned by interacti…
Quantum Geometry and Stability of Moiré Flatband Ferromagnetism
Fengcheng Wu, S. Das Sarma
Several moiré systems created by various twisted bilayers have manifested magnetism under flatband conditions leading to enhanced interaction effects. We theoretically study stabil…
Giant anomalous Hall effect in quasi-two-dimensional layered antiferromagnet CoNbS
Giulia Tenasini, Edoardo Martino, Nicolas Ubrig +8
The discovery of the anomalous Hall effect (AHE) in bulk metallic antiferromagnets (AFMs) motivates the search of the same phenomenon in two-dimensional (2D) systems, where a quant…
