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…
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 a…
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…
Topological Fermi-arc surface state covered by floating electrons on a two-dimensional electride
Chan-young Lim, Min-Seok Kim, Dong Cheol Lim +11
Two-dimensional electrides can acquire topologically non-trivial phases due to intriguing interplay between the cationic atomic layers and anionic electron layers. However, experim…
Atomic scale imaging of sign-changing order parameter in superconducting FeSe with Tunneling Andreev Reflection
Wonhee Ko, Sang Yong Song, Jiaqiang Yan +2
The pairing symmetry of the superconducting order parameter in iron-based superconductors has been a subject of debate, with various models proposing s-wave, d-wave, and mixed comb…
