Magneto-Optical Functions at the 3p resonances of Fe, Co, and Ni: Ab-initio description and experiment
F. Willems, S. Sharma, C. v. Korff Schmising +7
We present theoretical and experimental data on the magneto-optical contributions to the complex refractive index in the extreme ultraviolet (XUV) range covering the 3p resonances…
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…
L1 stacked binaries as candidates for hard magnets: FePt, MnAl and MnGa
Yu-ichiro Matsushita, Galia Madjarova, C. Felser +3
A novel strategy of stacking binary magnets to enhance the magneto crystalline anisotropy is explored. This strategy is used in the search for hard magnets by studying FePt/MnGa an…
Bootstrap kernel for organic low dimensional systems; PPV, pentacene and picene
S. Sharma, J. K. Dewhurst, E. K. U. Gross
We apply the bootstrap kernel within time dependent density functional theory to study one-dimensional chain of organic polymer poly-phenylene-vinylene and molecular crystals of pi…
Enhanced excitonic effects in the energy loss spectra of LiF and Ar at large momentum transfer
S. Sharma, J. K. Dewhurst, A. Sanna +2
It is demonstrated that the bootstrap kernel [\onlinecite{sharma11}] for finite values of crucially depends upon the matrix character of the kernel and gives results of t…
Bootstrap approximation for the exchange-correlation kernel of time-dependent density functional theory
S. Sharma, J. K. Dewhurst, A. Sanna +1
A new parameter-free approximation for the exchange-correlation kernel of time-dependent density functional theory is proposed. This kernel is expressed as an algorith…
