Electron spin resonance in scanning probe microscopy: From single‐spin spectroscopy to atomically engineered quantum operations

Abstract Electron spin resonance (ESR) is one of the most powerful spectroscopic methods for probing systems with unpaired electronic spins. Conventional ESR has usually relied on the detection of large spin ensembles, thereby averaging over local environments and suppressing mic...

Yu-Shiba-Rusinov-assisted Andreev transport in a molecular junction between superconductors

Magnetic impurities in superconductors host Yu-Shiba-Rusinov (YSR) bound states, whereas weak superconducting junctions sustain subharmonic charge transport through multiple Andreev reflections (MAR). We explore these phenomena using a molecular-scale junction created by placing...
