Emergence of Bogoliubov Fermi Surfaces in hybrid Al/InAs heterostructures
S. Feyrer, V. Dimic, I. Lobato +15
We investigate the microwave electrodynamics of a proximitized two-dimensional electron gas in hybrid superconductor/semiconductor heterostructures. Using lumped-element resonators…

From two dimensions to wire networks in a dice-lattice Josephson array
J. D. Bondar, L. Banszerus, W. Marshall +5
We investigate Josephson arrays consisting of a dice-lattice network of superconducting weak links surrounding rhombic plaquettes of proximitized semiconductor. Josephson coupling…

The hybrid Josephson rhombus: A superconducting element with tailored current-phase relation
L. Banszerus, C. W. Andersson, W. Marshall +4
Controlling the current-phase relation (CPR) of Josephson elements is essential for tailoring the eigenstates of superconducting qubits, tuning the properties of parametric amplifi…
