Preparation and STM study of clean Nb(111) surfaces
Julia J. Goedecke, Maciej Bazarnik, Roland Wiesendanger
Niobium with its highest transition temperature among all elemental superconductors has become a favorable substrate for realizing well-defined low-dimensional magnet-superconducto…
Correlation of Magnetism and Disordered Shiba Bands in Fe Monolayer Islands on Nb(110)
Julia J. Goedecke, Lucas Schneider, Yingqiao Ma +4
Two-dimensional (2D) magnet-superconductor hybrid systems are intensively studied due to their potential for the realization of 2D topological superconductors with Majorana edge mo…
The fundamental group functor as a Kan extension
Tomas Everaert, Julia Goedecke, Tim Van der Linden
We prove that the fundamental group functor from categorical Galois theory may be computed as a Kan extension.
Resolutions, higher extensions and the relative Mal'tsev axiom
Tomas Everaert, Julia Goedecke, Tim Van der Linden
We study how the concept of higher-dimensional extension which comes from categorical Galois theory relates to simplicial resolutions. For instance, an augmented simplicial object…
On satellites in semi-abelian categories: Homology without projectives
Julia Goedecke, Tim Van der Linden
Working in a semi-abelian context, we use Janelidze's theory of generalised satellites to study universal properties of the Everaert long exact homology sequence. This results in a…
A comparison theorem for simplicial resolutions
Julia Goedecke, Tim Van der Linden
It is well known that Barr and Beck's definition of comonadic homology makes sense also with a functor of coefficients taking values in a semi-abelian category instead of an abelia…
