Emergence of superfluid transport in a dynamical system of ultracold atoms
Joachim Brand, Andrey R. Kolovsky
The dynamics of a Bose-Einstein condensate is studied theoretically in a combined periodic plus harmonic external potential. Different dynamical regimes of stable and unstable coll…
Spin interferometry with electrons in nanostructures: A road to spintronic devices
U. Zuelicke
The wave nature of electrons in semiconductor nanostructures results in spatial interference effects similar to those exhibited by coherent light. The presence of spin-orbit coupli…
Electronic and spin properties of Rashba billiards
József Cserti, András Csordás, Ulrich Zülicke
Ballistic electrons confined to a billiard and subject to spin--orbit coupling of the Rashba type are investigated, using both approximate semiclassical and exact quantum--mechanic…
Andreev reflection at high magnetic fields: Evidence for electron and hole transport in edge states
J. Eroms, D. Weiss, J. De Boeck +2
We have studied magnetotransport in arrays of niobium filled grooves in an InAs/AlGaSb heterostructure. The critical field of up to 2.6 T permits to enter the quantum Hall regime.…
