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…
Bulk Fermi surfaces of the Dirac type-II semimetallic candidate NiTe2
Wenkai Zheng, Rico Schönemann, Shirin Mozaffari +7
Here, we present a study on the Fermi-surface of the Dirac type-II semi-metallic candidate NiTe via the temperature and angular dependence of the de Haas-van Alphen (dHvA) effe…
Multiple Dirac Nodes and Symmetry Protected Dirac Nodal Line in Orthorhombic -RhSi
Shirin Mozaffari, Niraj Aryal, Rico Schönemann +6
Owing to their chiral cubic structure, exotic multifold topological excitations have been predicted and recently observed in transition metal silicides like -RhSi. Herein, we re…
A numerically exact study of Weyl superconductivity
Peter Rosenberg, Niraj Aryal, Efstratios Manousakis
We study the interplay of interactions and topology in a pseudo-spin Weyl system, obtained from a minimally modified Hubbard model, using the numerically exact auxiliary-field quan…
Importance of electron correlations in understanding the photo-electron spectroscopy and the Weyl character of MoTe
Niraj Aryal, Efstratios Manousakis
We study the role of electron correlations in the presumed type II Weyl semimetallic candidate -MoTe by employing density functional theory (DFT) where the on-site Coulomb r…
Detailed study on the Fermi surfaces of the type-II Dirac semimetallic candidates PdTe2 and PtTe2
W. Zheng, R. Schönemann, N. Aryal +11
We present a detailed quantum oscillatory study on the Dirac type-II semimetallic candidates PdTe and PtTe \emph{via} the temperature and the angular dependence of the…
Bulk Fermi surfaces of the Dirac Type-II Semimetallic Candidates VAl3, NbAl3 and TaAl3
K. -W. Chen, X. Lian, Y. Lai +7
We report a de Haas-van Alphen (dHvA) effect study on the Dirac type-II semimetallic candidates \emph{M}Al (where, \emph{M} = V, Nb and Ta). The angular-dependence of their Fer…
Converting topological insulators into topological metals within the tetradymite family
K. -W. Chen, N. Aryal, J. Dai +14
We report the electronic band structures and concomitant Fermi surfaces for a family of exfoliable tetradymite compounds with the formula , obtained as a modificatio…
Fermi surface of the Weyl type-II metallic candidate WP2
R. Schönemann, N. Aryal, Q. Zhou +7
Weyl type-II fermions are massless quasiparticles that obey the Weyl equation and which are predicted to occur at the boundary between electron- and hole-pockets in certain semi-me…
Bulk Fermi-surface of the Weyl type-II semi-metallic candidate MoTe2
D. Rhodes, R. Schönemann, N. Aryal +15
The electronic structure of WTe and orthorhombic MoTe, are claimed to contain pairs of Weyl type-II points. A series of ARPES experiments claim a broad agreement with t…
