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…
Ab initio investigation of the topological Hall effect caused by magnetic skyrmions in Pd/Fe/Ir(111)
Adamantia Kosma, Philipp RüÃmann, Yuriy Mokrousov +2
We present an ab-initio computational analysis of the topological Hall effect arising from stable magnetic skyrmions in the Pd/Fe/Ir(111) film using non-collinear spin density func…
High-throughput magnetic co-doping and design of exchange interactions in a topological insulator
Rubel Mozumder, Johannes Wasmer, David Antognini Silva +2
Using high-throughput automation of ab-initio impurity embedding simulations, we created a database of and transition metal defects embedded into the prototypical topolog…
Low-energy modeling of three-dimensional topological insulator nanostructures
Eduárd Zsurka, Cheng Wang, Julian Legendre +6
We develop an accurate nanoelectronic modeling approach for realistic three-dimensional topological insulator nanostructures and investigate their low-energy surface-state spectrum…
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…
