Observation of Critical Current Minimum in Super-Honeycomb Josephson Junction Arrays
Melissa Mikalsen, Alexander-Georg Penner, Samuel D. Escribano +6
Superconductor-semiconductor Josephson junction arrays are a uniquely tunable platform for studying collective quantum phenomena, particularly in the regime where localized Andreev…
Interplay of superconductivity and ferromagnetism in ferromagnetic semiconductor-based Josephson junctions
Hirotaka Hara, Lukas Baker, Axel Leblanc +8
The interplay between superconductivity and ferromagnetism has long been pursued as a route to unconventional Josephson effects, yet suitable material platforms remain limited. Her…
Hybrid superinductance with Al/InAs
Junseok Oh, Ido Levy, Tyler Cowan +4
We report microwave spectroscopy of Josephson junctions chains made from an epitaxial Al/InAs heterostructure. The chains exhibit superinductance, with characteristic wave impedanc…
Enhanced superconducting diode effect in hybrid Josephson junctions
Peng Yu, Han Fu, William F. Schiela +7
The superconducting diode effect (SDE) has recently been observed in various systems, sparking interest in novel superconducting devices and offering a new platform to probe intrin…
Strongly anharmonic flux-tunable transmon based on InAs-Al 2D heterostructure
Shukai Liu, Arunav Bordoloi, Jacob Issokson +4
The gatemon qubits, made of transparent superconducting-semiconducting Josephson junctions, typically have even weaker anharmonicity than the opaque AlOx-junction transmons. Howeve…
Gate tunable enhancement of supercurrent in hybrid planar Josephson junctions
Peng Yu, Han Fu, William F. Schiela +6
Planar Josephson junctions (JJs) have emerged as a promising platform for the realization of topological superconductivity and Majorana zero modes. To obtain robust quasi one-dimen…
