Structural disorder and critical voltage scaling in Al/AlOx/Al Josephson junction arrays
Amanuel M. Berhane, Susan Coppersmith, Emma Mitchell +1
The insulating state of one-dimensional Josephson junction (JJ) arrays is governed by collective charge dynamics and disorder-induced pinning, resulting in a finite critical voltag…
Platforms for the realization and characterization of Tomonaga-Luttinger liquids
Isabelle Bouchoule, Roberta Citro, Tim Duty +5
The concept of a Tomonaga-Luttinger liquid (TLL) has been established as a fundamental theory for the understanding of one-dimensional quantum systems. Originally formulated as a r…
Phase transformation-induced superconducting aluminium-silicon alloy rings
B. C. Johnson, M. Stuiber, D. L. Creedon +8
The development of a materials platform that exhibits both superconducting and semiconducting properties is an important endeavour for a range of emerging quantum technologies. We…
A near-ideal degenerate parametric amplifier
Daniel J. Parker, Mykhailo Savytskyi, Wyatt Vine +5
Degenerate parametric amplifiers (DPAs) exhibit the unique property of phase-sensitive gain and can be used to noiselessly amplify small signals or squeeze field fluctuations benea…
Magnetic-field-induced parity effect in insulating Josephson junction chains
Timothy Duty, Karin Cedergren, Sergey Kafanov +2
We report the experimental manifestation of even-odd parity effects in the transport characteristics of insulating Josephson junction chains which occur as the superconducting gap…
Insulating Josephson-junction chains as pinned Luttinger liquids
Karin Cedergren, Roger Ackroyd, Sergey Kafanov +3
Quantum physics in one spatial dimension is remarkably rich, yet even with strong interactions and disorder, surprisingly tractable. This is due to the fact that the low-energy phy…
