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…
Giant periodic pseudo-magnetic fields in strained kagome magnet FeSn epitaxial films on SrTiO(111) substrate
Huimin Zhang, Michael Weinert, Lian Li
Quantum materials, particularly Dirac materials with linearly dispersing bands, can be effectively tuned by strain-induced lattice distortions leading to a pseudo-magnetic field th…
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…
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…
Flat-band based ferromagnetic semiconducting state in the graphitic CN monolayer
Chaoyu He, Yujie Liao, Tao Ouyang +3
A new set of lattice-models based on the hexagonal super-cells of the well-known honeycomb lattice with single-hole defect (HL-D-1/2N) are proposed to real…
Selective Trapping of Hexagonally Warped Topological Surface States in a Triangular Quantum Corral
Mu Chen, Yeping Jiang, Junping Peng +10
The surface of a three-dimensional topological insulator (TI) hosts two-dimensional massless Dirac fermions (DFs), the gapless and spin-helical nature of which yields many exotic p…
Higher-Order Topology in Monolayer FeSe
Gan Zhao, Haimen Mu, Huimin Zhang +1
Generally, the topological corner state in two-dimensional second-order topological insulator (2D SOTI) is equivalent to the well-known domain wall state, originated from the mass-…
Evidence for d-wave superconductivity in single layer FeSe/SrTiO3 probed by quasiparticle scattering off step edges
Zhuozhi Ge, Chenhui Yan, Huimin Zhang +3
The de Gennes extrapolation length is a direction dependent measure of the spatial evolution of the pairing gap near the boundary of a superconductor, and thus provides a viable me…
Origin of charge transfer and enhanced electron-phonon coupling in single unit-cell FeSe films on SrTiO3
Huimin Zhang, Ding Zhang, Xiaowei Lu +7
Interface charge transfer and electron-phonon coupling have been suggested to play a crucial role in the recently discovered high-temperature superconductivity of single unit-cell…

Can-Li Song, Hui-Min Zhang, Yong Zhong +6
We report on the emergence of two disconnected superconducting domes in alkali-metal potassium (K)-doped FeSe ultra-thin films grown on graphitized SiC(0001). The superconductivity…

Jun-Ping Peng, Jia-Qi Guan, Hui-Min Zhang +5
Molecular beam epitaxy is used to grow TiSe2 ultrathin films on graphitized SiC(0001) substrate. TiSe2films proceed via a nearly layer-by-layer growth mode and exhibit two dominant…
