Instability of the topological surface state in BiSe upon deposition of gold
A. Polyakov, C. Tusche, M. Ellguth +10
Momentum resolved photoemission spectroscopy indicates the instability of the Dirac surface state upon deposition of gold on the (0001) surface of the topological insulator BiS…
Swift thermal steering of domain walls in ferromagnetic MnBi stripes
Alexander Sukhov, Levan Chotorlishvili, Arthur Ernst +5
We predict a fast domain wall (DW) motion induced by a thermal gradient across a nanoscopic ferromagnetic stripe of MnBi. The driving mechanism is an exchange torque fueled by magn…
Exchange interaction and its tuning in magnetic binary chalcogenides
M. G. Vergniory, D. Thonig, M. Hoffmann +11
Using a first-principles Green's function approach we study magnetic properties of the magnetic binary chalcogenides Bi2Te3, Bi2Se3, and Sb2Te3. The magnetic coupling between trans…
Quantum effects on the loss function of Pb(111) thin films: an ab initio study
X. Zubizarreta, E. V. Chulkov, V. M. Silkin
A theoretical study of the surface energy-loss function of freestanding Pb(111) thin films is presented, starting from the single monolayer case. The calculations are carried apply…
Ab initio study of low-energy electronic collective excitations in bulk Pb: anisotropy and acoustic modes
X. Zubizarreta, V. M. Silkin, E. V. Chulkov
A theoretical study of the dynamical dielectric response of bulk lead at low energies is presented. The calculations are performed with full inclusion of the electron band structur…
First principles quasiparticle damping rates in bulk lead
X. Zubizarreta, V. M. Silkin, E. V. Chulkov
First principles calculations of the damping rates (inverse inelastic lifetimes) of low energy quasiparticles in bulk Pb are presented. Damping rates are obtained both for excited…
