Possible Experimental Realization of a Basic Z2 Topological Semimetal
Erik Haubold, Alexander Fedorov, Igor P. Rusinov +15
We report experimental and theoretical evidence that GaGeTe is a basic topological semimetal with three types of charge carriers: bulk-originated electrons and holes as well…
Energy scale of nematic ordering in the parent iron-based superconductor:BaFe2As2
Alexander Fedorov, Alexander Yaresko, Erik Haubold +6
Nematicity plays an important role in the physics of iron-based superconductors (IBS). Its microscopic origin and in particular its importance for the mechanism of high-temperature…
Massive Dirac fermions in layered BaZnBi
S. Thirupathaiah, D. Efremov, Y. Kushnirenko +7
Using angle-resolved photoemission spectroscopy (ARPES) and density functional theory (DFT) we study the electronic structure of layered BaZnBi. Our experimental results show n…
3D superconducting gap in FeSe from ARPES
Y. S. Kushnirenko, A. V. Fedorov, E. Haubold +7
We present a systematic angle-resolved photoemission spectroscopy study of the superconducting gap in FeSe. The gap function is determined in a full Brillouin zone including all Fe…
Spectroscopic evidence of topological phase transition in 3D Dirac semimetal Cd(AsP)
S. Thirupathaiah, I. Morozov, Y. Kushnirenko +9
We study the low-energy electronic structure of three-dimensional Dirac semimetal, Cd(AsP) [ = 0 and 0.34(3)], by employing the angle-resolved photoemission…
