Transparency-controlled multiple charge transfer in superconducting junctions with local shot-noise scanning tunneling spectroscopy
Yudai Sato, Maialen Ortego Larrazabal, Jian-Feng Ge +6
Charge transport in superconducting junctions at finite voltages is governed by Andreev reflections, including multiple Andreev reflections, which are processes that enable multipl…
Imaging the high-frequency charging dynamics of a single impurity in a semiconductor on the atomic scale
Maialen Ortego Larrazabal, Jiasen Niu, Stephen R. McMillan +4
As electronic devices approach the atomic limit, the charge dynamics of individual dopant atoms increasingly constrain performance, stability, and coherence. In scanning tunnelling…
Emergent Network of Josephson Junctions in a Kagome Superconductor
Tycho J. Blom, Matthijs Rog, Marieke Altena +5
Materials with a Kagome lattice are intensely studied because they host exotic states that combine strong correlations and topology. Recently, critical current oscillations were ob…
Cryogenic geometric anti-spring vibration isolation system
L. Feenstra, S. Domínguez-Calderón, K. van Oosten +9
The combination of low temperature and low vibration levels is key for ultrasensitive sensing applications such as scanning probe microscopy, large-mass quantum mechanics, and grav…
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…
Signatures of Amorphous Shiba State in FeTeSe
Jinwon Lee, Sanghun Lee, Andreas Kreisel +7
The iron-based superconductor FeTeSe is a peculiar material: it hosts a surface state with a Dirac dispersion, is a putative topological superconductor hosting Ma…
