Superconducting Qubits with Altermagnetic Josephson Junctions
Johanne Bratland Tjernshaugen, Morten Amundsen, Jacob Linder
Identifying a materials platform for creating qubits that are both tunable and resilient towards environmental noise is one of the main hurdles that need to be overcome to realize…
Dynamical Josephson Effect Between a Singlet and a Triplet Superconductor
Morten Amundsen, Niladri Banerjee, Igor ŽutiÄ
Phase-sensitive Josephson effect has long been central to identifying unconventional pairing symmetries in superconductors. Although the selection rules governing Josephson junctio…
Bending-strain effects in conventional superconductors and superconducting junctions
Kjell S. Heinrich, Henning G. Hugdal, Morten Amundsen +1
We consider the effect of bending-strain in thin films of clean, conventional superconductors (S), and the proximity-induced effect of this strain in SN bilayers with a normal meta…
Interface probe for antiferromagnets using geometric curvature
Tancredi Salamone, Magnus Skjærpe, Henning G. Hugdal +2
We propose that geometric curvature and torsion may be used to probe the quality of an uncompensated antiferromagnetic interface, using the proximity effect. We study a helix of an…
Josephson effect in a fractal geometry
Morten Amundsen, Vladimir JuriÄiÄ, Jabir Ali Ouassou
The Josephson effect is a hallmark signature of the superconducting state, which, however, has been sparsely explored in non-crystalline superconducting materials. Motivated by thi…
Electrical control of superconducting spin valves using ferromagnetic helices
Tancredi Salamone, Henning G. Hugdal, Morten Amundsen +1
The geometrical properties of a helical ferromagnet are shown theoretically to control the critical temperature of a proximity-coupled superconductor. Using the Usadel equation for…
