Magnetization dynamics and Majorana fermions in ferromagnetic Josephson junctions along the quantum spin Hall edge
Black-Schaffer, Annica; Linder, Jacob (Journal article; Peer reviewed, 2011)We investigate the interplay between ferromagnetic and superconducting order at the edge of a quantum spin Hall insulator. Using complementary analytical and self-consistent numerical approaches, we study a ferromagnetic ... -
Majorana fermions in spin-orbit-coupled ferromagnetic Josephson junctions
Black-Schaffer, Annica; Linder, Jacob (Journal article; Peer reviewed, 2011)We study all possible Majorana modes in two-dimensional spin-orbit-coupled ferromagnetic superconductor–normal state–superconductor (SNS) Josephson junctions and propose experiments to detect them. With the S region in a ... -
Quantum Ground State Control in Superconductor-Silicene Structures: 0-π transitions, φ₀-junctions, and Majorana bound states
Kuzmanovskii, Dushko; Linder, Jacob; Black-Schaffer, Annica (Journal article, 2016)We demonstrate theoretically that proximity-induced superconductivity in silicene offers the possibility to exert strong quantum ground state control. We show that electrically controlled 0-π transitions occur in Josephson ... -
Strongly anharmonic current-phase relation in ballistic graphene Josephson junctions
Black-Schaffer, Annica; Linder, Jacob (Journal article; Peer reviewed, 2010)Motivated by a recent experiment directly measuring the current-phase relation (CPR) in graphene under the influence of a superconducting proximity effect, we here study the temperature dependence of the CPR in ballistic ... -
Triplet proximity effect and odd-frequency pairing in graphene
Linder, Jacob; Black-Schaffer, Annica; Sudbø, Asle (Journal article; Peer reviewed, 2010)We study the interplay between proximity-induced superconductivity and ferromagnetism in graphene by self-consistently solving the Bogoliubov de Gennes equations on the honeycomb lattice. We find that a strong triplet ...
