Quantum-geometric dipole: a topological boost to flavor ferromagnetism in flat bands
Lei Chen, Sayed Ali Akbar Ghorashi, Jennifer Cano +2
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…

Phase Diagram and Spectroscopic Signatures of a Supersolid in Quantum Ising Magnet KCo(SeO)
Tong Chen, Alireza Ghasemi, Junyi Zhang +17
A supersolid is a quantum-entangled state of matter exhibiting the dual characteristics of superfluidity and solidity. Theory predicts that hard-core bosons with repulsive interact…

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…
