Journal ArticleDOI
Spin Generation Via Bulk Spin Current in Three Dimensional Topological Insulators
TL;DR: In this article, an external electric field creates a transverse pure spin current through the bulk of a three-dimensional topological insulator, which transports spins between the top and bottom surfaces.
Journal ArticleDOI
Out-of-plane instability and electron-phonon contribution to s- and d-wave pairing in high-temperature superconductors; LDA linear-response calculation for doped CaCuO2 and a generic tight-binding model
TL;DR: In this article, the equilibrium structure, energy bands, phonon dispersions, and s-and d-channel electron-phonon interactions (EPIs) were calculated for the infinite-layer superconductor CaCuO2 doped with 0.24 holes per CuO2.
Journal ArticleDOI
Colossal anomalous Nernst effect in a correlated noncentrosymmetric kagome ferromagnet
Tomoya Asaba,Vsevolod Ivanov,Sean Thomas,Sergey Y. Savrasov,Joe D. Thompson,Eric D. Bauer,Filip Ronning +6 more
TL;DR: In this paper, the anomalous Nernst effect (ANE) was shown to be present in magnetic actinide materials, and at least 148 Weyl nodes and two nodal lines were found in UCo$0.8}$Ru$ 0.2.
Journal ArticleDOI
Millimetre-long transport of photogenerated carriers in topological insulators.
Yasen Hou,Rui Wang,Rui Xiao,Luke McClintock,Henry Clark Travaglini,John P. Francia,Harry Fetsch,Onur Erten,Sergey Y. Savrasov,Baigeng Wang,Antonio Rossi,Inna Vishik,Eli Rotenberg,Dong Yu +13 more
TL;DR: Experimental evidence of formation and efficient transport of non-equilibrium excitons in Bi2-xSbxSe3 nanoribbons is reported, implying exciton condensation in topological materials with strong Coulomb interactions and vanishing electron effective mass.
Journal ArticleDOI
Emergence of topological nodal lines and type-II Weyl nodes in the strong spin-orbit coupling system InNb X 2 ( X = S ,Se)
Yongping Du,Xiangyan Bo,Di Wang,Erjun Kan,Chun-Gang Duan,Chun-Gang Duan,Sergey Y. Savrasov,Xiangang Wan +7 more
TL;DR: In this paper, the authors systematically investigated electronic structures and topological properties of layered materials with spin-orbit coupling (SOC) and showed nodal lines protected by mirror symmetry.
