Universal spin-polarization fluctuations in 1D wires with magnetic impurities
N. A. Mortensen, J. C. Egues
We study conductance and spin-polarization fluctuations in one-dimensional wires with spin-5/2 magnetic impurities (Mn). Our tight-binding Green function approach goes beyond mean…
Mesoscopic Coulomb Drag
Niels Asger Mortensen
This thesis describes the merging of the two fields of Coulomb drag and mesoscopic physics. The thesis presents a theory for Coulomb drag between two mesoscopic systems based on li…
Coulomb drag in phase-coherent mesoscopic structures - Numerical study of disordered 1D-wires
Niels Asger Mortensen, Karsten Flensberg, Antti-Pekka Jauho
We study Coulomb drag between two parallel disordered mesoscopic 1D-wires. By numerical ensemble averaging we calculate the statistical properties of the transconductance G_21 incl…
Coulomb drag in the mesoscopic regime
Niels Asger Mortensen, Karsten Flensberg, Antti-Pekka Jauho
We present a theory for Coulomb drag between two mesoscopic systems which expresses the drag in terms of scattering matrices and wave functions. The formalism can be applied to bot…
Mesoscopic fluctuations of Coulomb drag between quasi-ballistic 1D-wires
Niels Asger Mortensen, Karsten Flensberg, Antti-Pekka Jauho
Quasiballistic 1D quantum wires are known to have a conductance of the order of 2e^2/h, with small sample-to-sample fluctuations. We present a study of the transconductance G_12 of…
Diffusion equation and spin drag in spin-polarized transport
Karsten Flensberg, Thomas Stibius Jensen, Niels Asger Mortensen
We study the role of electron-electron interactions for spin polarized transport using the Boltzmann equation and derive a set of coupled transport equations. For spin polarized tr…
