Understanding multiscale disorder in superconducting nanowire single photon detectors
Nirjhar Sarkar, Ronan Gourgues, Yueh-Chun Wu +7
Superconducting nanowire single-photon detectors are central to applications across quantum information science. Yet, their performance is limited by the effects of disorder and el…
Detecting half-quantum superconducting vortices by spin-qubit relaxometry
Gábor B. Halász, Nirjhar Sarkar, Yueh-Chun Wu +3
Half-quantum vortices in spin-triplet superconductors are predicted to harbor Majorana zero modes and may provide a viable avenue to topological quantum computation. Here, we intro…
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…
Nanoscale magnetic ordering dynamics in a high Curie temperature ferromagnet
Yueh-Chun Wu, Gábor B. Halász, Joshua T. Damron +11
Thermally driven transitions between ferromagnetic and paramagnetic phases are characterized by critical behavior with divergent susceptibilities, long-range correlations, and spin…
