Testing the topological nature of end states in antiferromagnetic atomic chains on superconductors
Lucas Schneider, Philip Beck, Levente Rózsa +3
Edge states forming at the boundaries of topologically non-trivial phases of matter are promising candidates for future device applications because of their stability against local…
Proximity superconductivity in atom-by-atom crafted quantum dots
Lucas Schneider, Khai That Ton, Ioannis Ioannidis +4
Gapless materials in electronic contact with superconductors acquire proximity-induced superconductivity in a region near the interface. Numerous proposals build on this addition o…
Topological magnetic phase transition in Eu-based A-type antiferromagnets
Eliot Heinrich, Thore Posske, Benedetta Flebus
Recently, a colossal magnetoresistance (CMR) was observed in EuCdP -- a compound that does not fit the conventional mixed-valence paradigm. Instead, experimental evidence p…
Unique Signatures of Topological Phases in Two-Dimensional THz Spectroscopy
Felix Gerken, Thore Posske, Shaul Mukamel +1
We develop a microscopic theory for the two-dimensional spectroscopy of one-dimensional topological superconductors. We consider a ring geometry as a realization of the Kitaev chai…
Topological characterization of dynamic chiral magnetic textures using machine learning
Tim Matthies, Alexander F. Schäffer, Thore Posske +2
Recently proposed spintronic devices use magnetic skyrmions as bits of information. The reliable detection of those chiral magnetic objects is an indispensable requirement. Yet, th…
