Single-Molecule Junctions in Strong Optical Fields

Úterý, 09.06.2015 10:00 - 11:00

Joachim Reichert (Physik Department, TU München, Germany)

In order to advance the development of unimolecular electronic devices (e.g. film devices) it is mandatory to improve understanding of electron transport and its loss mechanisms in single molecules. In this aspect, multi-parameter studies are required to provide more information on such systems.

Effects of thermal spin fluctuations on the electronic properties of itinerant magnets: Surprises from ab initio calculations

Úterý, 09.06.2015 15:00 - 16:00

Kirill Belashchenko (University of Nebraska-Lincol)

Abstract: Thermal spin fluctuations are present in equilibrium in all magnetic materials. These fluctuations interact with electronic quasiparticles and induce temperature-dependent changes in such observables as the spectral densities, magnetocrystalline anisotropy, and transport properties. This talk will review surprising examples of such effects in metallic magnets found using first-principles calculations. Spin fluctuations are included in these calculations within the vector disordered local moment model.

Angle-resolved photoemission spectra of Heusler alloys: Ni2MnGa as a case study

Úterý, 16.06.2015 15:00

Václav Drchal (Oddělení teorie kondenzovaných látek, FzU AVCR)

Abstract: We have calculated the electronic structure and angle-resolved photoemission spectra of Heusler alloys from first principles using the TB-LMTO method. The disorder, caused either by non-stoichiometry, or by swapping of atoms between sublattices is treated within the CPA. Matrix elements are included within the dipole approximation.
