Rare-earth atoms on Nb(110) as a platform to engineer topological superconductivity
David Antognini Silva, Yu Wang, Nicolae Atodiresei +5
Helical spin textures in one-dimensional magnetic chains on superconductors can enable topological superconductivity and host Majorana zero modes, independent of the presence of in…

Inter-orbital Cooper pairing at finite energies in Rashba surface states
Philipp Rüßmann, Masoud Bahari, Stefan Blügel +1
Multi-band effects in hybrid structures provide a rich playground for unconventional superconductivity. We combine two complementary approaches based on density-functional theory (…
Helical Topological Superconducting Pairing at Finite Excitation Energies
Masoud Bahari, Song-Bo Zhang, Chang-An Li +4
We propose helical topological superconductivity away from the Fermi surface in three-dimensional time-reversal-symmetric odd-parity multiband superconductors. In these systems, pa…
Skyrmionic Spin Structures in Layered Fe5GeTe2 Up To Room Temperature
Maurice Schmitt, Thibaud Denneulin, András Kovács +12
The role of the crystal lattice, temperature and magnetic field for the spin structure formation in the 2D van der Waals magnet Fe5GeTe2 is a key open question. Using Lorentz trans…
Magnetic domain walls of the van der Waals material FeGeTe
Hung-Hsiang Yang, Namrata Bansal, Philipp Rüßmann +10
Among two-dimensional materials, FeGeTe has come to occupy a very important place owing to its ferromagnetic nature with one of the highest Curie temperatures among known v…

Philipp Rüßmann, Stefan Blügel
We report on the implementation of the Bogoliubov-de Gennes method into the JuKKR code [https: //jukkr.fz-juelich.de], an implementation of the relativistic all-electron, full-pote…
Incipient antiferromagnetism in the Eu-doped topological insulator BiTe
Abdul Tcakaev, Volodymyr B. Zabolotnyy, Celso I. Fornari +14
Rare earth ions typically exhibit larger magnetic moments than transition metal ions and thus promise the opening of a wider exchange gap in the Dirac surface states of topological…
