TaIrTe 4 : A ternary type-II Weyl semimetal
K. Koepernik,Deepa Kasinathan,D. V. Efremov,Seunghyun Khim,Sergey Borisenko,Bernd Büchner,Jeroen van den Brink,Jeroen van den Brink +7 more
TL;DR: In this article, the authors identify a third member of this family of topological semimetals as a third class of Weyl points, named TaIrTe, which is a type-II Weyl semimetal.
Journal ArticleDOI
Super-geometric electron focusing on the hexagonal Fermi surface of PdCoO2.
Maja D. Bachmann,Maja D. Bachmann,Aaron Sharpe,Aaron Sharpe,Arthur Barnard,Carsten Putzke,Carsten Putzke,Markus König,Seunghyun Khim,David Goldhaber-Gordon,David Goldhaber-Gordon,Andrew P. Mackenzie,Andrew P. Mackenzie,Philip J. W. Moll,Philip J. W. Moll +14 more
TL;DR: It is demonstrated that the nearly perfectly hexagonal Fermi surface of PdCoO2 gives rise to highly directional ballistic transport with enhanced electron self-focusing effects, suggesting a novel class of ballistic electronic devices exploiting the unique transport characteristics of strongly faceted Fermani surfaces.
Journal ArticleDOI
Maximal Rashba-like spin splitting via kinetic-energy-coupled inversion-symmetry breaking
Veronika Sunko,Veronika Sunko,H. Rosner,Pallavi Kushwaha,Seunghyun Khim,Federico Mazzola,L. Bawden,O. J. Clark,J. M. Riley,Deepa Kasinathan,Maurits W. Haverkort,Maurits W. Haverkort,Timur K. Kim,Moritz Hoesch,Jun Fujii,Ivana Vobornik,Andrew P. Mackenzie,Andrew P. Mackenzie,Phil D. C. King +18 more
TL;DR: The findings therefore provide opportunities for creating spin-textured states and suggest routes to interfacial control of inversion-symmetry breaking in designer heterostructures of oxides and other material classes.
Journal ArticleDOI
Experimental realization of type-II Weyl state in noncentrosymmetric TaIrTe 4
Erik Haubold,K. Koepernik,D. V. Efremov,Seunghyun Khim,Alexander Fedorov,Yevhen Kushnirenko,J. van den Brink,Sabine Wurmehl,Bernd Büchner,Timur K. Kim,Moritz Hoesch,Kazuki Sumida,Kazuaki Taguchi,Tomoki Yoshikawa,Akio Kimura,Taichi Okuda,Sergey Borisenko +16 more
TL;DR: In this article, the authors present experimental evidence for a type-II noncentrosymmetric Weyl semimetal with spin polarization in the direction along the Fermi arcs connecting four Weyl points.
Journal ArticleDOI
Evidence for dominant Pauli paramagnetic effect in the upper critical field of single-crystalline FeTe 0.6 Se 0.4
Seunghyun Khim,Jaewook Kim,Eun Sang Choi,Yunkyu Bang,Minoru Nohara,Hidenori Takagi,Kee Hoon Kim,Kee Hoon Kim +7 more
TL;DR: In this paper, the authors investigated the temperature dependence of the upper critical fields of a superconducting crystal by measuring its resistivity in static magnetic fields up to 45 T, and they showed that the Werthamer-Helfand-Hohenberg formula that includes both the Pauli limiting and the spin-orbit scattering can effectively describe both the {H}_{\text{c}2}^{ab}(T)$ and ${H}
