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…
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…
Tunable photon-photon correlations in waveguide QED systems with giant atoms
Wenju Gu, Lei Chen, Zhen Yi +2
We investigate the scattering processes of two photons in a one-dimensional waveguide coupled to two giant atoms. By adjusting the accumulated phase shifts between the coupling poi…
