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…
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…
Microwave Signatures of Topological Superconductivity in Planar Josephson Junctions
Barış Pekerten, David Brandão, Bassel Heiba Elfeky +4
Planar Josephson junctions provide a platform to host topological superconductivity which, through manipulating Majorana bound states (MBS), could enable fault-tolerant quantum com…
Microwave Andreev bound state spectroscopy in a semiconductor-based Planar Josephson junction
Bassel Heiba Elfeky, Krishna Dindial, David S. Brandão +13
By coupling a semiconductor-based planar Josephson junction to a superconducting resonator, we investigate the Andreev bound states in the junction using dispersive readout techniq…
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…
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…
Quasiparticle dynamics in epitaxial Al-InAs planar Josephson junctions
Bassel Heiba Elfeky, William M. Strickland, Jaewoo Lee +7
Quasiparticle (QP) effects play a significant role in the coherence and fidelity of superconducting quantum circuits. The Andreev bound states of high transparency Josephson juncti…
Superconducting Diode Effect Sign Change in Epitaxial Al-InAs Josepshon Junctions
Neda Lotfizadeh, William F. Schiela, Barış Pekerten +5
There has recently been a surge of interest in studying the superconducting diode effect (SDE) partly due to the possibility of uncovering the intrinsic properties of a material sy…
Evolution of -periodic Supercurrent in the Presence of In-plane Magnetic Field
Bassel Heiba Elfeky, Joseph J. Cuozzo, Neda Lotfizadeh +5
In the presence of a 4-periodic contribution to the current phase relation, for example in topological Josephson junctions, odd Shapiro steps are expected to be missing. While m…
Magneto-anisotropic weak antilocalization in near-surface quantum wells
S. M. Farzaneh, Mehdi Hatefipour, William F. Schiela +6
We investigate the effects of an in-plane magnetic field on the weak antilocalization signature of near-surface quantum wells lacking bulk and inversion symmetry. The measured magn…
Local Control of Supercurrent Density in Epitaxial Planar Josephson Junctions
Bassel H. Elfeky, Neda Lotfizadeh, William F. Schiela +9
The critical current response to an applied out-of-plane magnetic field in a Josephson junction provides insight into the uniformity of its current distribution. In Josephson junct…
Missing Shapiro steps in topologically trivial Josephson Junction on InAs quantum well
Matthieu C. Dartiailh, Joseph J. Cuozzo, William Mayer +4
Josephson junctions hosting Majorana fermions have been predicted to exhibit a 4 periodic current phase relation. The experimental consequence of this periodicity is the disappe…
