Local control of parity and charge in nanoscale superconducting lead islands
Stefano Trivini, Jon Ortuzar, Katerina Vaxevani +3
Small superconducting islands can exhibit charge quantization, where Coulomb interactions compete with Cooper pairing. Using scanning tunneling spectroscopy, we probe this interpla…

From local to collective superconductivity in proximitized graphene
Stefano Trivini, Tim Kokkeler, Jon Ortuzar +8
The superconducting proximity effect induces pairing correlations in metallic systems via Andreev scattering. This effect is particularly intriguing in graphene, as it enables two-…

Revealing inter-band electron pairing in a superconductor with spin-orbit coupling
Javier Zaldívar, Jon Ortuzar, Miguel Alvarado +8
Most superconducting mechanisms pair electrons within the same band, forming spin singlets. However, the discovery of multi-band superconductivity has opened new scenarios for pair…
