Dynamics of antiskyrmion shrinking
Frederik Austrup, Wolfgang Häusler, Michael Lau +1
Antiskyrmions are unstable in ferromagnetic systems with isotropic bulk or interfacial Dzyaloshinskii-Moriya interaction (DMI). We develop a continuum model for the shrinking dynam…
Interaction-induced conductance from zero modes in a clean magnetic graphene waveguide
Laura Cohnitz, Wolfgang Häusler, Alex Zazunov +1
We consider a waveguide formed in a clean graphene monolayer by a spatially inhomogeneous magnetic field. The single-particle dispersion relation for this waveguide exhibits a zero…
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…
Tunneling exponents in realistic quantum wires using the mean field approximation
Wolfgang Häusler, A. H. MacDonald
It is demonstrated that the charge Tomonaga-Luttinger parameter of quantum wires can be estimated accurately using the Hartree-Fock approximation if carried out self consiste…
