Ultrafast demagnetization in bulk vs thin films: an ab-initio study
K. Krieger, P. Elliott, T. Müller +4
We report on {\it ab-initio} simulations of the quantum dynamics of electronic charge and spin when subjected to intense laser pulses. By performing separate calculations for a Ni…
Demonstration of Optimal Control of Laser Induced Spin-Orbit Mediated Ultrafast Demagnetization
P. Elliott, K. Krieger, J. K. Dewhurst +2
Laser induced ultrafast demagnetization is the process whereby the magnetic moment of a ferromagnetic material is seen to drop significantly on a timescale of s of femtosec…
An efficient algorithm for time propagation within time-dependent density functional theory
J. K. Dewhurst, K. Krieger, S. Sharma +1
An efficient algorithm for time propagation of the time-dependent Kohn-Sham equations is presented. The algorithm is based on dividing the Hamiltonian into small time steps and ass…
Laser induced ultrafast demagnetization: an \emph{ab-initio} perspective
K. Krieger, J. K. Dewhurst, P. Elliott +2
Time-dependent density functional theory is implemented in an all electron solid-state code for the case of fully non-collinear spins. We use this to study laser induced demagnetiz…
Optimization Schemes for Selective Molecular Cleavage with Tailored Ultrashort Laser Pulses
Kevin Krieger, Alberto Castro, E. K. U. Gross
We present some approaches to the computation of ultra-fast laser pulses capable of selectively breaking molecular bonds. The calculations are based on a mixed quantum-classical de…
Depth Profile Reconstruction from Rutherford Backscattering Data
U. V. Toussaint, K. Krieger, R. Fischer +1
An adaptive kernel method in the Bayesian framework together with a new simulation program for Rutherford backscattering spectroscopy (RBS) have been applied to the analysis of RBS…
