Charge density wave in a band insulator
Md Shafayat Hossain, Wenhao Liu, Yuqi Zhang +20
Charge density wave (CDW) implies a periodic modulation of the charge density. Typically observed in metallic systems, CDWs arise from Fermi surface instabilities, resulting in the…
Interlayer Charge-density-wave Vector Phase Induced Structural Chirality
Sen Shao, Wei-Chi Chiu, Tao Hou +21
Chiral charge density waves (CDWs) have attracted intense interest due to their exotic quantum properties, yet the microscopic origin of structural chirality emerging from correlat…
Superconductivity and a van Hove singularity confined to the surface of a topological semimetal
Md Shafayat Hossain, Rajibul Islam, Zi-Jia Cheng +16
The interplay between electronic topology and superconductivity is the subject of great current interest in condensed matter physics. For example, superconductivity induced on the…
Broken symmetries associated with a Kagome chiral charge order
Zi-Jia Cheng, Md Shafayat Hossain, Qi Zhang +17
Chirality or handedness manifests in all fields of science, ranging from cell biology, molecular interaction, and catalysis to different branches of physics. In condensed matter ph…
Discovery of a topological exciton insulator with tunable momentum order
Md Shafayat Hossain, Tyler A. Cochran, Yu-Xiao Jiang +27
Correlated topological materials often maintain a delicate balance among physical symmetries: many topological orders are symmetry protected, while most correlated phenomena arise…
Field induced density wave in a kagome superconductor
Md Shafayat Hossain, Qi Zhang, Julian Ingham +19
On the kagome lattice, electrons benefit from the simultaneous presence of band topology, flat electronic bands, and van Hove singularities, forming competing or cooperating orders…
