Correlated topological-polarization surface states in the narrow-gap insulator FeSb2
Takahiro Iwagaki, Hideki Matsuoka, Ginta Hoshino +7
Strong electron correlations and band topology each generate rich quantum phases, but conflicting elemental requirements have largely kept them apart. Topological polarization offe…
Ab initio study of magnetoresistance effect in antiferromagnetic tunnel junction
Katsuhiro Tanaka, Yuta Toga, Susumu Minami +4
The antiferromagnets with the time-reversal symmetry broken magnetic structures possess a finite spin splitting in the momentum space, and may contribute to a realization of a fini…
Enhancement of the Thermoelectric Figure of Merit in the Dirac Semimetal CdAs by Band-Structure and -Filling Control
Markus Kriener, Takashi Koretsune, Ryotaro Arita +2
Topological materials attract a considerable research interest because of their characteristic band structure giving rise to various new phenomena in quantum physics. Beside this,…
Orbital paramagnetism without density of states enhancement in nodal-line semimetal ZrSiS
Soshun Ozaki, Hiroyasu Matsuura, Ikuma Tateishi +2
Unconventional orbital paramagnetism without enhanced density of states was recently discovered in the nodal-line semimetal ZrSiS. We propose a novel interband mechanism, linked to…
High-throughput calculations of antiferromagnets hosting anomalous transport phenomena
Takuya Nomoto, Susumu Minami, Yuki Yanagi +3
We develop a high-throughput computational scheme based on cluster multipole theory to identify new functional antiferromagnets. This approach is applied to 228 magnetic compounds…
Electron-doped magnetic Weyl semimetal LixCo3Sn2S2 by bulk-gating
Hideki Matsuoka, Yukako Fujishiro, Susumu Minami +4
Manipulating carrier density through gate effects, both in electrostatic charge storage and electrochemical intercalation mode, offers powerful control over material properties, al…
Emergence of high-mobility carriers in topological kagome bad metal MnSn by intense photoexcitation
Takuya Matsuda, Tomoya Higo, Kenta Kuroda +13
Kagome-lattice materials offer novel playgrounds of exploring topologically nontrivial states of electrons under influence of many-body interactions. A noncollinear kagome antiferr…
Topological Kagome magnet Co3Sn2S2 thin flakes with high electron mobility and large anomalous Hall effect
M. Tanaka, Y. Fujishiro, M. Mogi +9
Magnetic Weyl semimetals attract considerable interest not only for their topological quantum phenomena but also as an emerging materials class for realizing quantum anomalous Hall…
Large magneto-optical Kerr effect and imaging of magnetic octupole domains in an antiferromagnetic metal
Tomoya Higo, Huiyuan Man, Daniel B. Gopman +14
When a polarized light beam is incident upon the surface of a magnetic material, the reflected light undergoes a polarization rotation. This magneto-optical Kerr effect (MOKE) has…
Tailoring band-structure and band-filling in a simple cubic (IV, III) - VI superconductor
M. Kriener, M. Kamitani, T. Koretsune +3
Superconductivity and its underlying mechanisms are one of the most active research fields in condensed-matter physics. An important question is how to enhance the transition tempe…
Evidence for Magnetic Weyl Fermions in a Correlated Metal
K. Kuroda, T. Tomita, M. -T. Suzuki +19
Recent discovery of both gapped and gapless topological phases in weakly correlated electron systems has introduced various relativistic particles and a number of exotic phenomena…
