Laser-induced ultrafast demagnetization and perpendicular magnetic anisotropy reduction in a CoTb thin film with stripe domains
M. Hennes, A. Merhe, X. Liu +15
We use time-resolved x-ray resonant magnetic scattering (tr-XRMS) at the Co M- and Tb O-edges to study ultrafast demagnetization in an amorphous CoTb allo…
Tuning the pseudospin polarization of graphene by a pseudo-magnetic field
Alexander Georgi, Peter Nemes-Incze, Ramon Carrillo-Bastos +16
One of the intriguing characteristics of honeycomb lattices is the appearance of a pseudo-magnetic field as a result of mechanical deformation. In the case of graphene, the Landau…
The weak side of strong topological insulators
Björn Sbierski, Martin Schneider, Piet W. Brouwer
Strong topological insulators may have nonzero weak indices. The nonzero weak indices allow for the existence of topologically protected helical states along line defects of the la…
Electronic transport in graphene with particle-hole-asymmetric disorder
Max Hering, Martin Schneider, Piet W. Brouwer
We study the conductivity of graphene with a smooth but particle-hole-asymmetric disorder potential. Using perturbation theory for the weak-disorder regime and numerical calculatio…
Induced Matter Brane Gravity and Einstein Static Universe
Y. Heydarzade, F. Darabi
We investigate stability of the Einstein static universe against the scalar, vector and tensor perturbations in the context of induced matter brane gravity. It is shown that in the…
Density of states as a probe of electrostatic confinement in graphene
Martin Schneider, Piet W. Brouwer
We theoretically analyze the possibility to confine electrons in single-layer graphene with the help of metallic gates, via the evaluation of the density of states of such a gate-d…
Quantum corrections to transport in graphene: a trajectory-based semiclassical analysis
Martin Schneider, Piet W. Brouwer
We review a calculation of the quantum corrections to electrical transport in graphene using the trajectory-based semiclassical method. Compared to conventional metals, for graphen…
Interplay of Aharonov-Bohm and Berry phases in gate-defined graphene quantum dots
Julia Heinl, Martin Schneider, Piet W. Brouwer
We study the influence of a magnetic flux tube on the possibility to electrostatically confine electrons in a graphene quantum dot. Without magnetic flux tube, the graphene pseudos…
Semiclassical theory of the interaction correction to the conductance of antidot arrays
Martin Schneider, Georg Schwiete, Piet W. Brouwer
Electron-electron interactions are responsible for a correction to the conductance of a diffusive metal, the "Altshuler-Aronov correction" . Here we study the counterpart…
Resonant scattering in graphene with a gate-defined chaotic quantum dot
Martin Schneider, Piet W. Brouwer
We investigate the conductance of an undoped graphene sheet with two metallic contacts and an electrostatically gated island (quantum dot) between the contacts. Our analysis is bas…
Theory of non-equilibrium electronic Mach-Zehnder interferometer
Martin Schneider, Dmitry A. Bagrets, Alexander D. Mirlin
We develop a theoretical description of interaction-induced phenomena in an electronic Mach-Zehnder interferometer formed by integer quantum Hall edge states (with ν=1 and 2 channe…
