Tunable competing optical excitation pathways in the topological surface states of BiTe
Shin Yokoyama, Takahito Takeda, Nagi Suzuki +9
Understanding coherent optical responses of topological surface states (TSSs) requires disentangling excitation pathways from the electronic band structure. Here, using angle-resol…
Termination-Dependent Surface States and Magnetic Fingerprints of Chiral Helimagnet Cr1/3TaS2
Bo Liang, Xue Li, Congcong Le +36
Chiral helimagnets based on intercalated transition-metal dichalcogenides, characterized by nano-scale spin ordering, provide a powerful route to engineer chiral spin textures (e.g…
Strongly Anisotropic Spin and Orbital Rashba Effect at a Tellurium - Noble Metal Interface
B. Geldiyev, M. Ünzelmann, P. Eck +19
We study the interplay of lattice, spin and orbital degrees of freedom in a two-dimensional model system: a flat square lattice of Te atoms on a Au(100) surface. The atomic structu…
Laser-based angle-resolved photoemission spectroscopy with micrometer spatial resolution and detection of three-dimensional spin vector
Takuma Iwata, T. Kousa, Y. Nishioka +11
We have developed a state-of-the-art apparatus for laser-based spin- and angle-resolved photoemission spectroscopy with micrometer spatial resolution (micro-SARPES). This equipment…
Domain dependent Fermi arcs observed in a striped phase dichalcogenide
T. Mizokawa, A. Barinov, V. Kandyba +11
Angle-resolved photoemission spectromicroscopy on IrTe2 reveals evolution of mesoscopic striped domains across its first order phase transition at about 280 K. The striped texture…
Experimental observation and spin texture of Dirac node arcs in tetradymite topological metals
J. Dai, E. Frantzeskakis, N. Aryal +10
We report the observation of a non-trivial spin texture in Dirac node arcs, novel topological objects formed when Dirac cones of massless particles extend along an open one-dimensi…
