Three-atom magnets with strong substrate coupling: a gateway towards non-collinear spin processing
J. Hermenau, J. Ibañez-Azpiroz, Chr. Hübner +10
A cluster composed of a few magnetic atoms assembled on the surface of a nonmagnetic substrate is one suitable realization of a bit for future concepts of spin-based information te…
General scheme for stable single and multiatom nanomagnets according to symmetry selection rules
M. Marciani, C. Hübner, B. Baxevanis
At low temperature, information can be stored in the orientation of the localized magnetic moment of an adatom. However, scattering of electrons and phonons with the nanomagnet lea…
Two-dimensional Josephson vortex lattice and anomalously slow decay of the Fraunhofer oscillations in a ballistic SNS junction with a warped Fermi surface
V. P. Ostroukh, B. Baxevanis, A. R. Akhmerov +1
The critical current of a Josephson junction is an oscillatory function of the enclosed magnetic flux , because of quantum interference modulated with periodicity . We…
Quench dynamics of fermion-parity switches in a Josephson junction
B. Tarasinski, D. Chevallier, Jimmy A. Hutasoit +2
A Josephson junction may be driven through a transition where the superconducting condensate favors an odd over an even number of electrons. At this switch in the ground-state ferm…
Even-odd flux quanta effect in the Fraunhofer oscillations of an edge-channel Josephson junction
B. Baxevanis, V. P. Ostroukh, C. W. J. Beenakker
We calculate the beating of and periodic oscillations of the flux-dependent critical supercurrent through a quantum spin-Hall insulator between two supercondu…
Symmetry effects on spin switching of adatoms
Christoph Hübner, Benjamin Baxevanis, Alexander Ako Khajetoorians +1
Highly symmetric magnetic environments have been suggested to stabilize the magnetic information stored in magnetic adatoms on a surface. Utilized as memory devices such systems ar…
