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…

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…
