Driving nuclear spin transitions on a single atom using STM — •Cristina Mier Gonzalez, Hester Vennema, Evert Stolte, Jinwon Lee, and Sander Otte — Delft University of Technology, 2628 CJ Delft, The Netherlands
Nuclear spins are highly isolated from its electronic environment compared to electron spins. This degree of isolation makes nuclear spins a promising platform for quantum technologies [1]. The development of ESR-STM has made possible the indirect measurement of nuclear spins on single atoms through the hyperfine interaction [2]. More recently, single-shot read-out on Ti isotopes has shown a nuclear lifetime of about 5 seconds [3].
In this work we aim to controllably address nuclear spin transitions using ESR-STM. We propose a double resonance measurement scheme to controllably drive the nuclear spin of a 47Ti isotope (I=5/2). Our study paves the way for coherent manipulation of single nuclear spins using STM.
