The magneto-optical response of Fe and Ni during ultrafast demagnetization is studied experimentally and theoretically. We have performed pump-probe experiments in the transverse magneto-optical Kerr effect (T-MOKE) geometry using photon energies tha

The authors use ultrashort laser pulses to generate a highly non-equilibrium excited state in simple metallic ferromagnets, iron and nickel, in order to elucidate the differences between magnetic excitations and magnons. Utilizing extreme ultraviolet

In this article we perform a critical assessment of different known methods for the analytical continuation of bosonic functions, namely the maximum entropy method, the non-negative least-square method, the non-negative Tikhonov method, the Pad\'e ap

We propose a new efficient permanent magnet, ${\mathrm{SmCoNiFe}}_{3}$, which is a development of the well-known ${\mathrm{SmCo}}_{5}$ prototype. More modern neodymium magnets of the Nd-Fe-B type have an advantage over ${\mathrm{SmCo}}_{5}$ because o

NTRODUCTION The reproducibility of results is one of the underlying principles of science. An observation can only be accepted by the scientific community when it can be confirmed by independent studies. However, reproducibility does not come easily.

At ambient pressure the element cerium shows a metastable (${t}_{1/2}\ensuremath{\sim}40$ years) double-hexagonal close-packed $\ensuremath{\beta}$ phase that is positioned between two cubic phases, $\ensuremath{\gamma}$ and $\ensuremath{\alpha}$. Wi

The ill-posed analytic continuation problem for Green's functions and self-energies is investigated by revisiting the Pad\'{e} approximants technique. We propose to remedy the well-known problems of the Pad\'{e} approximants by performing an average

We here present a code for performing analytic continuation of fermionic Green’s functions and self-energies as well as bosonic susceptibilities on a graphics processing unit (GPU). The code is based on the sampling method introduced by Mishchenko

We provide an approach for the identification of the electronic and magnetic configurations of ferromagnetic Fe after an ultrafast decrease or increase of the magnetization. The model is based on the well-grounded assumption that, after an ultrafast
