Link between supercurrent diode and anomalous Josephson effect revealed by gate-controlled interferometry
Simon Reinhardt, Tim Ascherl, Andreas Costa +9
In Josephson diodes the asymmetry between positive and negative current branch of the current-phase relation leads to a polarity-dependent critical current and Josephson inductance…
Charge-4e supercurrent in a two-dimensional InAs-Al superconductor-semiconductor heterostructure
Carlo Ciaccia, Roy Haller, Asbjørn C. C. Drachmann +4
Superconducting qubits with intrinsic noise protection offer a promising approach to improve the coherence of quantum information. Crucial to such protected qubits is the encoding…
Josephson diode effect derived from short-range coherent coupling
Sadashige Matsuo, Takaya Imoto, Tomohiro Yokoyama +6
Superconducting devices with broken time-reversal and spatial-inversion symmetries can exhibit novel superconducting phenomena. The observation of superconducting diode effects, wh…
Engineering of anomalous Josephson effect in coherently coupled Josephson junctions
Sadashige Matsuo, Takaya Imoto, Tomohiro Yokoyama +6
A Josephson junction (JJ) is a key device in the development of superconducting circuits, wherein a supercurrent in the JJ is controlled by the phase difference between the two sup…
Gate Tunable Josephson Diode in Proximitized InAs Supercurrent Interferometers
Carlo Ciaccia, Roy Haller, Asbjørn C. C. Drachmann +4
The Josephson diode (JD) is a non-reciprocal circuit element that supports a larger critical current in one direction compared to the other. This effect has gained a growing intere…
Phase-dependent Andreev molecules and superconducting gap closing in coherently coupled Josephson junctions
Sadashige Matsuo, Takaya Imoto, Tomohiro Yokoyama +8
The Josephson junction (JJ) is an essential element of superconducting (SC) devices for both fundamental and applied physics. The short-range coherent coupling of two adjacent JJs…
