PhD Thesis defense: Superconducting Phenomena at the Nanoscale

Superconductors exhibit macroscopic quantum ordering that allows their unique properties to emerge even at mesoscopic scales, enabling practical applications in electronics and quantum computing. This distinctive behavior makes superconductivity one of the most studied topics in condensed matter physics, valued for both its theoretical elegance and broad physical relevance. In this thesis, we investigate superconductivity at the nanoscale using Scanning Tunneling Microscopy and Ultra-High-Vacuum (UHV) synthesis. By combining superconductors with atomic magnetism, normal metals, and confinement near the pairing limit, we examine these systems’ unique nanoscale behaviors both experimentally and theoretically
