Artifical atoms in interacting graphene quantum dots
Wolfgang Häusler, Reinhold Egger
We describe the theory of few Coulomb-correlated electrons in a magnetic quantum dot formed in graphene. While the corresponding nonrelativistic (Schrödinger) problem is well under…
Spin conversion rates due to dipolar interactions in mono-isotopic quantum dots at vanishing spin-orbit coupling
Wolfgang Häusler, Peter Hänggi
Dipolar interaction between the magnetic moments of electrons is studied as a source for electron spin decay in quantum dots or arrays of quantum dots. This magnetic interaction wi…
Dephasing in Rashba spin precession along mutlichannel quantum wires and nanotubes
Wolfgang Häusler
Coherent Rashba spin precession along interacting multi-mode quantum channels is investigated, revisiting the theory of coupled Tomonaga-Luttinger liquids. We identify susceptibili…
Rashba precession in quantum wires
Wolfgang Häusler
The length over which electron spins reverse direction due to the Rashba effect when injected with an initial polarization along the axes of a quantum wire is investigated theoreti…
Rashba spin splitting in different quantum channels
Wolfgang Häusler
Rashba precession of spins moving along a one-subband quantum channel is calculated. The quantitative influence of unoccupied higher subbands depends on the shape of the transversa…
Gapped Phases of Quantum Wires
O. A. Starykh, D. L. Maslov, W. Häusler +1
We investigate possible nontrivial phases of a two-subband quantum wire. It is found that inter- and intra-subband interactions may drive the electron system of the wire into a gap…
