Benítez-Llambay P, Masset F, Koenigsberger G, Szulágyi J.
PMID: 25832403
Nature. 2015 Apr 02;520(7545):63-5. doi: 10.1038/nature14277.

Planetary systems are born in the disks of gas, dust and rocky fragments that surround newly formed stars. Solid content assembles into ever-larger rocky fragments that eventually become planetary embryos. These then continue their growth by accreting leftover material...

Light-Matter Interaction at Surfaces in the Spatiotemporal Limit of Macroscopic Models.

Physical review letters

Lucchini M, Castiglioni L, Kasmi L, Kliuiev P, Ludwig A, Greif M, Osterwalder J, Hengsberger M, Gallmann L, Keller U.

Phys Rev Lett. 2015 Sep 25;115(13):137401. doi: 10.1103/PhysRevLett.115.137401. Epub 2015 Sep 22.

What is the spatiotemporal limit of a macroscopic model that describes the optoelectronic interaction at the interface between different media? This fundamental question has become relevant for time-dependent photoemission from solid surfaces using probes that resolve attosecond electron dynamics...

Robust spin polarization and spin textures on stepped Au(111) surfaces.

We present a non-comprehensive review of some representative experimental studies in crystalline condensed matter systems where the effects of intense ultrashort light pulses are probed using x-ray diffraction and photoelectron spectroscopy. On an ultrafast (sub-picosecond) time scale, conventional concepts...

Femtosecond manipulation of spins, charges, and ions in nanostructures, thin films, and surfaces.

Cuprous oxide ([Formula: see text]) is a promising material for photoelectrochemical energy conversion due to its small direct band gap, high absorbance, and its Earth-abundant constituents. High conversion efficiencies require transport of photoexcited charges to the interface without energy...

Illuminating a nano-sized metallic tip with ultrashort laser pulses leads to the emission of electrons due to multiphoton excitations. As optical fields become stronger, tunnelling emission directly from the Fermi level becomes prevalent. This can generate coherent electron waves...
