This Colloquium discusses the recent progress in understanding the properties of spin-split
superconductors under nonequilibrium conditions. Recent experiments and theories …

Spectroscopic measurements with low-temperature scanning tunneling microscopes have
been used very successfully for studying not only individual atomic or molecular spins on …

Pair density wave (PDW) states are defined by a spatially modulating superconductive order
parameter. To search for such states in transition-metal dichalcogenides (TMDs), we used …

A scanning tunneling microscope (STM) with a magnetic tip that has a sufficiently strong spin
polarization can be used to map the sample's spin structure down to the atomic scale but …

Recent advances in scanning probe techniques rely on the chemical functionalization of the
probe-tip termination by a single molecule. The success of this approach opens the prospect …

Spin-resolved scanning tunneling microscopy is employed to quantitatively determine the
spin polarization of the magnetic field-split Kondo state. Tunneling conductance spectra of a …

Generating highly spin-polarized currents at the nanoscale is essential for spin current
manipulations and spintronic applications. We find indications for up to 100% spin-polarized …

Controlling spin-polarized currents at the nanoscale is of immense importance for high-
density magnetic data storage and spin-based logic devices. As electronic devices are …

The magnetic exchange coupling between magnetic impurities and a superconductor
induce so-called Yu-Shiba-Rusinov (YSR) states which undergo a quantum phase transition …

The current-voltage characteristics of a voltage-biased Josephson junction in the low
conductance regime of an ultra-low temperature scanning tunneling microscope (STM) is …
