Orientation-resolved tunnel spectroscopy of a triplet superconductor
Marcel Strohmeier, Andriy Smolyanyuk, Karsten Held +5
Although Cooper pairs in superconductors generally condense into a spin-singlet state, spin-triplet superconductivity has attracted sustained interest since it enables dissipationl…
Nonmonotonic temperature dependence of the thermopower of atomic-size gold contacts
Thomas B. Möller, Marcel Strohmeier, Johannes Boneberg +3
We report measurements of the thermopower of atomic-size gold contacts realized by the mechanically controllable break junction (MCBJ) technique over a temperature range from 18 K…
Benchmarking Current-to-Voltage Amplifiers for Quantum Transport Measurements
J. Escorza, G. Pellicer, T. de Ara +4
Accurate electrical amplification is essential in molecular electronics for measuring conductance through atomic and molecular junctions, where currents often span several orders o…
Spin-polarized transport in copper-oxide atomic junctions revealed by anomalous shot-noise behavior in presence of the Kondo effect
Marcel Strohmeier, Samanwita Biswas, Wolfgang Belzig +2
Noise measurements provide a valuable tool for revealing spin polarization effects in the electronic transport through quantum coherent conductors. We present an extension of the L…
Van der Waals superconducting electronics: materials, devices and circuit integration
Angelo Di Bernardo, Elke Scheer
Van der Waals (vdW) superconductors - atomically thin crystalline materials that can be stacked into more complex heterostructures - have opened a promising avenue for superconduct…
Imaging of Gate-Controlled Suppression of Superconductivity via the Meissner Effect
P. J. Scheidegger, K. J. Knapp, U. Ognjanovic +5
It was recently discovered that supercurrents flowing through thin superconducting nanowires can be quenched by a gate voltage. This gate control of supercurrents, known as the GCS…

Nico Sprinkart, Elke Scheer, Angelo Di Bernardo
The Berry phase is a fundamental concept in quantum mechanics with profound implications for understanding topological properties of quantum systems. This tutorial provides a compr…
High-performance gate-controlled superconducting switches: large output voltage and reproducibility
Leon Ruf, Elke Scheer, Angelo Di Bernardo
Logic circuits consist of devices that can be controlled between two distinct states. The recent demonstration that a superconducting current flowing in a constriction can be contr…
Unveiling unconventional magnetism at the surface of SrRuO
Rosalba Fittipaldi, Roman Hartmann, Maria Teresa Mercaldo +23
Materials with strongly correlated electrons exhibit physical properties that are often difficult to predict as they result from the interactions of large numbers of electrons comb…
Gate-controlled supercurrent effect in dry-etched Dayem bridges of non-centrosymmetric niobium rhenium
