Many-Body Localization: Transitions in Spin Models
John Schliemann, Joao Vitor I. Costa, Paul Wenk +1
We study the transitions between ergodic and many-body localized phases in spin systems, subject to quenched disorder, including the Heisenberg chain and the central spin model. In…
Persistent spin textures and currents in wurtzite nanowire-based quantum structures
Michael Kammermeier, Adrian Seith, Paul Wenk +1
We explore the spin and charge properties of electrons in wurtzite semiconductor nanowires where radial and axial confinement leads to tubular or ring-shaped quantum structures. Ac…
Floquet-Drude conductivity
Martin Wackerl, Paul Wenk, John Schliemann
This letter presents a generalization of the Drude conductivity for systems which are exposed to periodic driving. The probe bias is treated perturbatively by using the Kubo formul…
In-plane magnetoelectric response in bilayer graphene
Michael Kammermeier, Paul Wenk, Ulrich Zülicke
A graphene bilayer shows an unusual magnetoelectric response whose magnitude is controlled by the valley-isospin density, making it possible to link magnetoelectric behavior to val…
Ultralong spin lifetimes in one-dimensional semiconductor nanowires
Florian Dirnberger, Michael Kammermeier, Jan König +9
We experimentally demonstrate ultralong spin lifetimes of electrons in the one-dimensional (1D) quantum limit of semiconductor nanowires. Optically probing single wires of differen…
Spin relaxation in wurtzite nanowires
Michael Kammermeier, Paul Wenk, Florian Dirnberger +2
We theoretically investigate the D'yakonov-Perel' spin relaxation properties in diffusive wurtzite semiconductor nanowires and their impact on the quantum correction to the conduct…
