A One-Step Model of Photoemission from Single Crystal Surfaces
Siddharth Karkare, Weishi Wan, Jun Feng +2
In this paper, we present a 3-D one step photoemission model that can be used to calculate the quantum efficiency and momentum distributions of electrons photoemitted from ordered…
Discovery of two-dimensional Dirac nodal line fermions in monolayer Cu2Si
Baojie Feng, Botao Fu, Shusuke Kasamatsu +18
Topological nodal line semimetals, a novel quantum state of materials, possess topologically nontrivial valence and conduction bands that touch at a line near the Fermi level. The…
Signatures of exciton condensation in a transition metal dichalcogenide
Anshul Kogar, Melinda S. Rak, Sean Vig +9
Bose condensation has shaped our understanding of macroscopic quantum phenomena, having been realized in superconductors, atomic gases, and liquid helium. Excitons are bosons that…
Spin Texture in Type-II Weyl Semimetal WTe2
Baojie Feng, Yang-Hao Chan, Ya Feng +15
We determine the band structure and spin texture of WTe2 by spin- and angle-resolved photoemission spectroscopy (SARPES). With the support of first-principles calculations, we reve…
Proving Nontrivial Topology of Pure Bismuth by Quantum Confinement
S. Ito, B. Feng, M. Arita +13
The topology of pure Bi is controversial because of its very small (10 meV) band gap. Here we perform high-resolution angle-resolved photoelectron spectroscopy measurements s…
