Observation of a singular Weyl point surrounded by charged nodal walls in PtGa
J. -Z. Ma, Q. -S. Wu, M. Song +17
Constrained by the Nielsen-Ninomiya no-go theorem, in all so-far experimentally determined Weyl semimetals (WSMs) the Weyl points (WPs) always appear in pairs in the momentum space…
Dirac Fermions and Possible Weak Antilocalization in LaCuSb
J. R. Chamorro, A. Topp, Y. Fang +7
Layered heavy-metal square-lattice compounds have recently emerged as potential Dirac fermion materials due to bonding within those sublattices. We report quantum transport and spe…
Modular Arithmetic with Nodal Lines: Drumhead Surface States in ZrSiTe
Lukas Muechler, Andreas Topp, Raquel Queiroz +5
We study the electronic structure of the nodal line semimetal ZrSiTe both experimentally and theoretically. We find two different surface states in ZrSiTe - topological drumhead su…
Band renormalization of blue phosphorus on Au(111)
E. Golias, M. Krivenkov, A. Varykhalov +2
Most recently, theoretical calculations predicted the stability of a novel two-dimensional phosphorus honeycomb lattice named blue phosphorus. Here, we report on the growth of blue…
Surface floating 2D bands in layered nonsymmorphic semimetals: ZrSiS and related compounds
Andreas Topp, Raquel Queiroz, Andreas Grüneis +10
In this work, we present a model of the surface states of nonsymmorphic semimetals. These are derived from surface mass terms that lift the high degeneracy imposed in the band stru…
Suppression of electron scattering resonances in graphene by quantum dots
M. Krivenkov, D. Marchenko, J. Sánchez-Barriga +2
Transmission of low-energetic electrons through two-dimensional materials leads to unique scattering resonances. These resonances contribute to photoemission from occupied bands wh…
