Crossed Andreev reflection revealed by self-consistent Keldysh-Usadel formalism
Johanne Bratland Tjernshaugen, Morten Amundsen, Jacob Linder
Crossed Andreev reflection (CAR) is a process that creates entanglement between spatially separated electrons and holes. Such entangled pairs have potential applications in quantum…

The interaction between two impurity spins provides vital information about the host system and has been suggested to form a building block in quantum computation and spintronic de…
Superconducting phase diagram and spin diode effect via spin accumulation
Johanne Bratland Tjernshaugen, Morten Amundsen, Jacob Linder
Spin-split superconductors offer new functionality compared to conventional superconductors such as diode-effects and efficient thermoelectricity. The superconducting state can nev…
Grain-boundary topological superconductor
Morten Amundsen, Vladimir Juričić
Majorana zero modes (MZMs) are of central importance for modern condensed matter physics and quantum information due their non-Abelian nature, which thereby offers the possibility…
Colloquium: Spin-orbit effects in superconducting hybrid structures
Morten Amundsen, Jacob Linder, Jason W. A. Robinson +2
Spin-orbit coupling (SOC) relates to the interaction between an electron's motion and its spin, and is ubiquitous in solid-state systems. Although the effect of SOC in normal-state…
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…

The quasiclassical theory of superconductivity provides a methodology to study emergent phenomena in hybrid structures comprised of superconductors interfaced with other materials.…
Unconventional Meissner screening induced by chiral molecules in a conventional superconductor
Hen Alpern, Morten Amundsen, Roman Hartmann +12
The coupling of a superconductor to a different material often results in a system with unconventional superconducting properties. A conventional superconductor is a perfect diamag…

We show that corner Majorana zero modes in a two-dimensional topological superconductor can be controlled by the manipulation of the parent wave superconducting order. A…
Interfacial control of vortex-limited critical current in type II superconductor films
Marius K. Hope, Morten Amundsen, Dhavala Suri +2
In a small subset of type II superconductor films, the critical current is determined by a weakened Bean-Livingston barrier posed by the film surfaces to vortex penetration into th…
Planar graphene-NbSe Josephson junctions in a parallel magnetic field

Thin transition metal dichalcogenides sustain superconductivity at large in-plane magnetic fields due to Ising spin-orbit protection, which locks their spins in an out-of-plane ori…

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…
