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…
