For the past decade, Majorana quasiparticles have become one of the hot topics in
condensed matter research. Besides the fundamental interest in the realization of particles …

Yu-Shiba-Rusinov (YSR) bound states appear when a magnetic atom interacts with a
superconductor. Here, we report on spin-resolved spectroscopic studies of YSR states …

Tin adatoms on a Si (111) substrate with a one-third monolayer coverage form a two-
dimensional triangular lattice with one unpaired electron per site. These electrons order into …

The scattering of superconducting pairs by magnetic impurities on a superconducting
surface leads to pairs of sharp in-gap resonances known as Yu-Shiba-Rusinov (YSR) bound …

Interfacing magnetism with superconducting condensates is rapidly emerging as a viable
route for the development of innovative quantum technologies. In this context, the …

Exploration of topology is central in condensed matter physics and applications to fault-
tolerant quantum information. The bulk-boundary correspondence and tenfold classification …

The exchange interaction of a brominated Co-porphyrin molecule with the Cooper pair
condensate of Pb (111) is modified by reducing the Co–surface separation. The stepwise …

Vortices in topological superconductors are predicted to host Majorana bound states (MBSs)
as exotic quasiparticles. In recent experiments, the spatially non-split zero-energy vortex …

The hybridization of Yu-Shiba-Rusinov (YSR) states in dimers of magnetic impurities leads
to molecularlike bonding and antibonding modes. In many-impurity systems, the interaction …

We propose cyclic refrigeration in solid state, employing a gas of magnetic field vortices in a
type-II superconductor—also known as fluxons—as the cooling agent. Refrigeration cycles …
