Journal Article
Blair, A., & Hampshire, D. (2022). Critical current density of superconducting-normal-superconducting Josephson junctions and polycrystalline superconductors in high magnetic fields. Physical Review Research, 4(2), Article 023123. https://doi.org/10.1103/physrevresearch.4.023123

We investigate the in-field critical current density Jc (B) of superconducting-normal-superconducting (SNS) Josephson junctions (JJs) and polycrystalline superconducting systems with grain boundaries modeled as Josephson-type planar defects, both ana...

Journal Article
Haddon, C., Blair, A., Schoofs, F., & Hampshire, D. (2022). Computational Simulations Using Time-Dependent Ginzburg–Landau Theory for Nb–Ti-Like Microstructures. IEEE Transactions on Applied Superconductivity, 32(4), Article 8800105. https://doi.org/10.1109/tasc.2022.3156916

Simulations based on time-dependent Ginzburg–Landau theory are employed to determine the critical current for a model system which represents a Nb–Ti-like pinning landscape at low drawing strain. The system consists of ellipsoids of normal metal, wit... Read More about Computational Simulations Using Time-Dependent Ginzburg–Landau Theory for Nb–Ti-Like Microstructures.

Critical Current Densities through Josephson Junctions in Low Magnetic Fields (2022)
Journal Article
Din, B., Blair, A., Schoofs, F., & Hampshire, D. (2022). Critical Current Densities through Josephson Junctions in Low Magnetic Fields. IEEE Transactions on Applied Superconductivity, 32(4), Article 8000805. https://doi.org/10.1109/tasc.2022.3156908

Understanding the properties of grain boundaries in polycrystalline superconductors is essential for optimizing their critical current density. Here, we provide computational simulations of 2D Josephson junctions (JJs) in low magnetic fields using ti...
