Tapping-mode SQUID-on-tip Microscopy with Proximity Josephson Junctions
Matthijs Rog, Tycho J. Blom, Daan B. Boltje +6
Studying nanoscale dynamics is essential for understanding quantum materials and advancing quantum chip manufacturing. Still, it remains a major challenge to measure non-equilibriu…
Recombination of localized quasiparticles in disordered superconductors
Steven A. H. de Rooij, Remko Fermin, Kevin Kouwenhoven +6
Disordered superconductors offer new impedance regimes for quantum circuits, enable a pathway to protected qubits, and can improve superconducting detectors due to their high kinet…
Time-reversal symmetry breaking in microscopic single-crystal SrRuO devices
Remko Fermin, Matthijs Rog, Guido Stam +6
Time-reversal symmetry breaking superconductivity is a quintessential unconventional quantum state. In Josephson junctions, time-reversal symmetry breaking manifests itself in the…
Triplet supercurrents in lateral Josephson junctions with a half-metallic ferromagnet
Yao Junxiang, Remko Fermin, Mariona Cabero +2
In the area of superconducting spintronics, spin triplet supercurrents in half-metallic ferromagnets (HMFs) could yield dissipationless spin transport over large distances, and hig…
