Spin-relaxation in superconducting graphene
ORAL
Abstract
2D materials in the proximity to a superconductor are expected to host a
wide spectrum of different phenomena. In my talk I will focus on
spin-relaxation in graphene proximitized by an s-wave superconductor.
Adatom impurities can affect spin-relaxation via locally enhanced
spin-orbit coupling (SOC) and local magnetic moments. I will discuss
their impact on quasiparticle spin-relaxation with an attempt to
disentangle contributions from the local SOC and local magnetic
moments. Moreover, I will analyze the stability of the induced local
magnetic moments and the emergence of Yu-Shiba-Rusinov (YSR) bound
states in such proximity induced superconducting systems.
