Sharp periodic Ge concentration modulations beyond the conduction band valley wavevector in nuclear spin-free Si quantum wells
Ivo Rahlff, Carsten Richter, Martin Schmidbauer +13
Periodic Ge modulations within strained Si quantum wells in SiGe heterostructures offer a route to deterministically enhance conduction-band valley splitting in Si, a key requireme…
Valley Splittings in Si/SiGe Heterostructures from First Principles
Lukas Cvitkovich, Tancredi Salamone, Christoph Wilhelmer +3
We compute valley splittings in Si/SiGe superlattices using ab initio density functional theory (DFT). This first-principle approach is expected to provide an excellent description…
Valley physics in the two bands model for SiGe heterostructures and spin qubits
Tancredi Salamone, Biel Martinez Diaz, Jing Li +2
We discuss the choice and implementation of inter-valley potentials in the so-called two bands model for the opposite , or valleys of silicon…
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…
Non-constant geometric curvature for tailored spin-orbit coupling and chirality in superconductor-magnet heterostructures
Alv Johan Skarpeid, Henning G. Hugdal, Tancredi Salamone +2
We show that tailoring the geometric curvature profile of magnets can be used for bespoke design of an effective non-relativistic spin-orbit coupling, which may be used to control…
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…
High magnetic field superconductivity in a two-band superconductor
Tancredi Salamone, Henning G. Hugdal, Sol H. Jacobsen +1
When applying an external magnetic field to a superconductor, orbital and Pauli paramagnetic pairbreaking effects govern the limit of the upper critical magnetic field that can be…
Curvature control of the superconducting proximity effect in diffusive ferromagnetic nanowires
Tancredi Salamone, Henning G. Hugdal, Morten Amundsen +1
Coupling a conventional s-wave superconductor to a ferromagnet allows, via the proximity effect, to generate superconducting triplet correlations. This feature can be employed to a…
Curvature-induced long ranged supercurrents in diffusive SFS Josephson Junctions, with dynamic transition
Tancredi Salamone, Mathias B. M. Svendsen, Morten Amundsen +1
We report that spin supercurrents can be induced in diffusive SFS Josephson junctions without any magnetic misalignment or intrinsic spin orbit coupling. Instead, the pathway to sp…
