Gate-tunable Josephson diodes in magic-angle twisted bilayer graphene
A. Rothstein, R. J. Dolleman, L. Klebl +8
We report low-temperature measurements of two adjacent, gate-defined Josephson junctions (JJs) in magic-angle twisted bilayer graphene (MATBG) at a moiré filling factor near $ν=…
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…
Voltage-controlled synthesis of higher harmonics in hybrid Josephson junction circuits
L. Banszerus, W. Marshall, C. W. Andersson +4
We report measurements of the current-phase relation of two voltage-controlled semiconductor-superconductor hybrid Josephson junctions (JJs) in series. The two hybrid junctions beh…
