Quantum-Geometry-Induced Superconductivity near a Fractional Chern Insulator
Haoyu Hu, Lei Chen
The paper analytically studies how quantum‑geometric effects in a partially filled Chern band can generate superconductivity adjacent to a fractional Chern insulator, using a coupl…

Quantum critical metals and loss of quasiparticles
Haoyu Hu, Lei Chen, Qimiao Si
Strange metals develop near quantum critical points in a variety of strongly correlated systems. Some of the issues that are central to the field include how the quantum-critical s…

Metallic quantum criticality enabled by flat bands in a kagome lattice
Lei Chen, Fang Xie, Shouvik Sur +4
Strange metals arise in a variety of platforms for strongly correlated electrons, ranging from the cuprates, heavy fermions to flat band systems. Motivated by recent experiments in…
