Gate-driven Switching Dynamics in a Fully Suspended Superconducting Nanowire
Matthijs Rog, Giacomo Trupiano, Filippo Antola +4
A gate voltage can suppress the critical current of a superconducting nanowire, and various scenarios have been proposed to describe these observations. The key difficulty is that…
Tunable Thermoelectric Superconducting Heat Pipe and Diode
F. Antola, A. Braggio, G. De Simoni +1
Efficient heat management at cryogenic temperatures is crucial for superconducting quantum technologies. This study demonstrates the controlled manipulation of the heat flow and he…
Back-action supercurrent diodes
Daniel Margineda, Alessandro Crippa, Elia Strambini +8
Back-action refers to a response that retro-acts on a system to tailor its properties with respect to an external stimulus. This effect is at the heart of many electronic devices s…
Circuit-theoretic phenomenological model of an electrostatic gate-controlled bi-SQUID
Thomas X. Kong, Jace Cruddas, Jonathan Marenkovic +4
A numerical model based on a lumped circuit element approximation for a bi-superconducting quantum interference device (bi-SQUID) operating in the presence of an external magnetic…
A gate- and flux-controlled supercurrent diode
Federico Paolucci, Giorgio De Simoni, Francesco Giazotto
Non-reciprocal charge transport in supercurrent diodes (SDs) polarized growing interest in the last few years for its potential applications in superconducting electronics (SCE). S…
Gate control of superconductivity in mesoscopic all-metallic devices
Claudio Puglia, Giorgio De Simoni, Francesco Giazotto
It was recently demonstrated the possibility to tune, through the application of a control gate voltage, the superconducting properties of mesoscopic devices based on Bardeen-Coope…
Field-Effect Control of Metallic Superconducting Systems
Federico Paolucci, Giorgio De Simoni, Paolo Solinas +4
Despite metals are believed to be insensitive to field-effect and conventional Bardeen-Cooper-Schrieffer (BCS) theories predict the electric field to be ineffective on conventional…

We demonstrate the first \textit{all-metallic} mesoscopic superconductor-normal metal-superconductor (SNS) field-effect controlled Josephson transistors (SNS-FETs) and show their f…
Ultra-efficient superconducting Dayem bridge field-effect transistor
Federico Paolucci, Giorgio De Simoni, Elia Strambini +2
Superconducting field-effect transitor (SuFET) and Josephson field-effect transistor (JoFET) technologies take advantage of electric field induced control of charge carrier concent…
Metallic supercurrent field-effect transistor
G. De Simoni, F. Paolucci, P. Solinas +2
In their original formulation of superconductivity, the London brothers predicted the exponential suppression of an field inside a superconductor over the so-called…

Giorgio De Simoni, Lukas Mahler, Vincenzo Piazza +5
We present a planar laser diode based on a simple fabrication scheme compatible with virtually any geometry accessible by standard semiconductor lithography technique. We show that…
