Ultra-long-range spin coupling in graphene revealed by atomically resolved spin excitations
Beatriz Viña-Bausá, Antonio. T. Costa, Joao Henriques +6
Magnetic interactions between localized spins-1/2 play a central role in quantum magnetism, spin-based quantum computing, and quantum simulation. The range and strength of these in…

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…
