Fabrication and Structural Analysis of Trilayers for Tantalum Josephson Junctions with TaO Barriers
Raahul Potluri, Rohin Tangirala, Jiangteng Liu +6
Tantalum (Ta) has emerged as a promising low-loss material, enabling record coherence times in superconducting qubits. This enhanced performance is largely attributed to its stable…
Plastic vortex creep and dimensional crossovers in the highly anisotropic superconductor HgBaCuO
Haley M. Cole, Michael B. Venuti, Brian Gorman +3
In type-II superconductors exposed to magnetic fields between upper and lower critical values, and , penetrating magnetic flux forms a lattice of vortices whose mo…
Designing high-performance superconductors with nanoparticle inclusions: comparisons to strong pinning theory
Sarah C. Jones, Masashi Miura, Ryuji Yoshida +4
One of the most promising routes for achieving unprecedentedly high critical currents in superconductors is to incorporate dispersed, non-superconducting nanoparticles to control t…
Perspective: Challenges and Transformative Opportunities in Superconductor Vortex Physics
Serena Eley, Andreas Glatz, Roland Willa
In superconductors, the motion of vortices introduces unwanted dissipation that is disruptive to applications. Fortunately, material defects can immobilize vortices, acting as vort…
Vortex phases and glassy dynamics in the highly anisotropic superconductor HgBaCuO
Serena Eley, Roland Willa, Mun K. Chan +2
We present an extensive study of vortex dynamics in a high-quality single crystal of HgBaCuO (Hg1201), a highly anisotropic superconductor that is a model system for st…
Glassy Dynamics in a heavy ion irradiated NbSe2 crystal
Serena Eley, Karen Khilstrom, Roxana Fotovat +7
Fascination with glassy states has persisted since Fisher introduced the vortex-glass as a new thermodynamic phase that is a true superconductor that lacks conventional long-range…
Accelerated vortex dynamics across the magnetic 3D-to-2D crossover in disordered superconductors
Serena Eley, Roland Willa, Masashi Miura +4
Disorder can have remarkably disparate consequences in superconductors, driving superconductor-insulator transitions in ultrathin films by localizing electron pairs and boosting th…
Universal Lower Limit on Vortex Creep in Superconductors
Serena Eley, Masashi Miura, Boris Maiorov +1
Superconductors are excellent testbeds for studying vortices, topological excitations that also appear in superfluids, liquid crystals, and Bose-Einstein condensates. Vortex motion…
Decoupling and tuning competing effects of different types of defects on flux creep in irradiated YBaCuO coated conductors
S. Eley, M. Leroux, M. W. Rupich +7
YBaCuO coated conductors (CCs) have achieved high critical current densities () that can be further increased through the introduction of additi…
History-dependent dissipative vortex dynamics in superconducting arrays
Malcolm Durkin, Ian Mondragon-Shem, Serena Eley +2
We perform current(I)-voltage(V) measurements on low resistance superconductor-normal-superconductor arrays in finite magnetic fields, focusing on the dilute vortex population regi…
Rapid Doubling of the Critical Current of YBaCuO Coated Conductors for Viable High-Speed Industrial Processing
Maxime Leroux, Karen J. Kihlstrom, Sigrid Holleis +11
We demonstrate that 3.5-MeV oxygen irradiation can markedly enhance the in-field critical current of commercial 2nd generation superconducting tapes with an exposure time of just o…
Fate of global superconductivity in arrays of long SNS junctions
Serena Eley, Sarang Gopalakrishnan, Paul M. Goldbart +1
Normal-metal films overlaid with arrays of superconducting islands undergo Berezinskii-Kosterlitz-Thouless (BKT) superconducting transitions at a temperature . We present…
Approaching Zero-Temperature Metallic States in Mesoscopic Superconductor-Normal-Superconductor Arrays
Serena Eley, Sarang Gopalakrishnan, Paul M. Goldbart +1
Systems of superconducting islands placed on normal metal films offer tunable realizations of two-dimensional (2D) superconductivity; they can thus elucidate open questions regardi…
