Microwave radiometry of a quantum-critical, hybrid Josephson array
Kristen W. Léonard, Anton V. Bubis, Melissa Mikalsen +6
Arrays of Josephson junctions can be tuned through anomalous metallic, quantum-critical, and insulating regimes. We introduce a new experimental probe, capturing microwave radiatio…
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…
Gate-tunable polarity inversions and three-fold rotation symmetry of the superconducting diode effect
William F. Schiela, Melissa Mikalsen, Daniel Crawford +4
The superconducting diode effect is an asymmetry in the critical current with respect to the supercurrent polarity. One impetus driving recent interest in the effect is its depende…
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…
Geometric dependence of critical current magnitude and nonreciprocity in planar Josephson junctions
William F. Schiela, Melissa Mikalsen, William M. Strickland +1
Planar Josephson junctions in a magnetic field exhibit the superconducting diode effect, by which the critical current magnitude depends on the polarity of the transport current. A…
Gatemonium: A Voltage-Tunable Fluxonium
William M. Strickland, Bassel Heiba Elfeky, Lukas Baker +6
We present a new style of fluxonium qubit, gatemonium, based on an all superconductorsemiconductor hybrid platform. The linear inductance is achieved using six hundred planar Al-In…
