Direct Observation of Channelised Supercurrents in a Kagome Superconductor
Matthijs Rog, Tycho J. Blom, Reinier Q. Regter +9
Superconductors are many-body quantum states in which current flows without dissipation. Theory predicts that supercurrents follow a relatively simple spatial pattern in both conve…
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…
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…
Young's double-slit experiment with anisotropic GHz surface acoustic waves on gallium arsenide
Thomas Steenbergen, Matteo Fisicaro, Krystian Czerniak +3
We demonstrate Young's double-slit experiment with GHz surface acoustic waves (SAWs) on gallium arsenide (GaAs). This experiment differs from the well-known optical case due to the…
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…
