Negative-resistance models for parametrically flux-pumped superconducting quantum interference devices
K. M. Sundqvist, P. Delsing
A Superconducting QUantum Interference Device (SQUID) modulated by a fast oscillating magnetic flux can be used as a parametric amplifier, providing gain with very little added noi…

Charge transport in InAs nanowire Josephson junctions
Simon Abay, Daniel Persson, Henrik Nilsson +5
We present an extensive experimental and theoretical study of the proximity effect in InAs nanowires connected to superconducting electrodes. We fabricate and investigate devices w…

The pumpistor: a linearized model of a flux-pumped SQUID for use as a negative-resistance parametric amplifier
K. M. Sundqvist, S. Kintaş, M. Simoen +4
We describe a circuit model for a flux-driven SQUID. This is useful for developing insight into how these devices perform as active elements in parametric amplifiers. The key conce…
