Charge density wave induced gapped nodal line
Sergey Alekseev, Lei Chen, Jennifer Cano
We investigate the interplay between charge density wave (CDW) order and topological nodal-line states in square-net materials. Our Ginzburg-Landau theory predicts a CDW instabilit…

Quantum-geometric dipole: a topological boost to flavor ferromagnetism in flat bands
Lei Chen, Sayed Ali Akbar Ghorashi, Jennifer Cano +1
Robust flavor-polarized phases are a striking hallmark of many flat-band moiré materials. In this work, we trace the origin of this spontaneous polarization to a lesser-known quant…
