Fingerprinting superconductors by disentangling Andreev and quasiparticle currents across tunable tunnel junctions
Petro Maksymovych, Sang Yong Song, Benjamin Lawrie +2
Tunneling Andreev reflection (TAR) spectroscopy offers a powerful new approach to fingerprint superconducting pairing symmetry at the atomic scale. By leveraging the exponential se…
Ultranarrow Bright Single-Photon Emitters in Diamond with Strong Broadband Phonon Decoupling
Swetapadma Sahoo, Péter Udvarhelyi, Jaden Li +6
Single-photon emitters are fundamental building blocks for quantum information processing, communication and sensing. However, unwanted interactions with bulk phonons in their host…
Real-space visualization of orbital-selective superconductivity in FeSe
Sang Yong Song, Gábor B. Halász, Jiaqiang Yan +2
We investigate the orbitally resolved superconducting properties of bulk FeSe using scanning tunneling microscopy (STM). We find that the spectral weights of both the large …
Non-perturbative cathodoluminescence microscopy of beam-sensitive materials
Malcolm Bogroff, Gabriel Cowley, Ariel Nicastro +9
Cathodoluminescence microscopy is now a well-established and powerful tool for probing the photonic properties of nanoscale materials, but in many cases, nanophotonic materials are…
Nanoscale control over single vortex motion in an unconventional superconductor
Sang Yong Song, Chengyun Hua, Gábor B. Halász +4
To realize braiding of vortex lines and understand the basic properties of the energy landscape for vortex motion, precise manipulation of superconducting vortices on the nanoscale…
