Tracking attosecond electronic coherences using phase-manipulated extreme ultraviolet pulses

The recent development of ultrafast extreme ultraviolet (XUV) coherent light sources bears great potential for a better understanding of the structure and dynamics of matter. Promising routes are advanced coherent control and nonlinear spectroscopy schemes ...

Method and device for sensing humidity with reversible molecular dimerization

László Forró, Primoz Rebernik Ribic, Arnaud Magrez, Endre Horvath

The present invention relates to the use of reversible dimerization of methylene blue (MB) for sensing humidity. The invention preferably uses titanate nanowires coated with MB. The self-organizational properties of MB on the surface of this nanostructured ...

Tuning the length dispersion of multi-walled carbon nanotubes by ball milling

László Forró, Arnaud Magrez, Claudio Grimaldi, Richard Gaal, Marijana Mionic Ebersold, Rita Smajda, Primoz Rebernik Ribic

The statistical analysis of the length distribution of catalytic chemical vapour deposition synthesized multi-walled carbon nanotubes cut by planetary ball milling is reported. The nanotube lengths follow a log-normal distribution in a broad range of grind ...

Interaction of a point charge with the surface of a uniaxial dielectric

Primoz Rebernik Ribic

We analyze the force on a point charge moving at relativistic speeds parallel to the surface of a uniaxial dielectric. Two cases are examined: a lossless dielectric with no dispersion and a dielectric with a plasma-type response. The treatment focuses on t ...

The physics behind free electron lasers (FELs) based on magnetostatic and optical undulators

Giorgio Margaritondo, Primoz Rebernik Ribic

By explicitly writing the equations of motion for highly relativistic electrons in an electromagnetic field we show the equivalence between the magnetostatic and optical (laser) undulator-based free electron lasers (FELs). In order to gain insight into the ...

Can a Metal Surface Repel Electric Charges?

Primoz Rebernik Ribic

We show that the interaction between a surface and a charge packet moving parallel to it can become repulsive above a critical relativistic energy. We find that this is true for a lossless dielectric surface and also for a Drude metallic surface-in apparen ...

Dye metachromasy on titanate nanowires: sensing humidity with reversible molecular dimerization

László Forró, Arnaud Magrez, Primoz Rebernik Ribic, Endre Horvath

We report on the reversible dimerization of methylene blue (MB) on titanate nanowires. The self-organizational properties of MB on the surface of this nanostructured material studied by spectroscopic means revealed that the light absorption properties of t ...

A simplified description of X-ray free-electron lasers

Giorgio Margaritondo, Primoz Rebernik Ribic

It is shown that an elementary semi-quantitative approach explains essential features of the X-ray free-electron laser mechanism, in particular those of the gain and saturation lengths. Using mathematical methods and derivations simpler than complete theor ...

Graphene nanoribbons produced by the oxidative unzipping of single-wall carbon nanotubes

Giorgio Margaritondo, Primoz Rebernik Ribic

Graphene nanoribbons were synthesized by oxidative unzipping of single-wall carbon nanotubes (SWCNTs). The nanoribbons produced from SWCNTs were characterized using FT-IR, Raman and X-ray photoelectron spectroscopy. For the morphological study of the produ ...
