Tomonaga Luttinger liquid in the topological edge channel of multilayer FeSe
Huimin Zhang, Qiang Zou, Lian Li
A two dimensional topological insulator exhibits helical edge states topologically protected against single particle backscattering. Such protection breaks down, however, when elec…
Revealing intrinsic vortex-core states in Fe-based superconductors through machine-learning-driven discovery
Yueming Guo, Hu Miao, Qiang Zou +5
Electronic states within superconducting vortices hold crucial information about paring mechanisms and topology. While scanning tunneling microscopy/spectroscopy(STM/S) can image t…
Deciphering alloy composition in superconducting single-layer FeSe1-xSx on SrTiO3(001) substrates by machine learning of STM/S data
Qiang Zou, Basu Dev Oli, Huimin Zhang +3
Scanning tunneling microscopy (STM) is a powerful technique for imaging atomic structure and inferring information on local elemental composition, chemical bonding, and electronic…
Realization of multiple charge density waves in NbTe2 at the monolayer limit
Yusong Bai, Zemin Pan, Jinghao Deng +9
Abstract: Layered transition-metal dichalcogenides (TMDCs) down to the monolayer (ML) limit provide a fertile platform for exploring charge-density waves (CDWs). Though bulk NbTe2…
Tuning quantum paramagnetism and d-wave superconductivity in single-layer iron chalcogenides by chemical pressure
Qiang Zou, Basu Dev Oli, Huimin Zhang +4
By substituting S into single-layer FeSe/SrTiO3, chemical pressure is applied to tune its paramagnetic state that is modeled as an incoherent superposition of spin-spiral states. T…
