Coherent Phonon Coupling to Individual Bloch States in Photoexcited Bismuth

E. Papalazarou, J. Faure, J. Mauchain +8

We investigate the temporal evolution of the electronic states at the bismuth (111) surface by means of time and angle resolved photoelectron spectroscopy. The binding energy of bu…

Ion-matter interaction: the three dimensional version of the thermal spike model. Application to nanoparticle irradiation with swift heavy ions

Ch. Dufour, V. Khomenkov, G. Rizza +1

In the framework of swift heavy ion - matter interaction, the thermal spike has proved its worth since nearly two decades. This paper deals with the necessary refinement of the com…

Nucleation of single wall carbon nanotubes of various chiralities

Francois Beuneu

A simple model for the nucleation and growth of single wall carbon nanotubes from a graphene sheet at the surface of a metallic catalyst saturated in carbon is developed. It enable…

Anisotropy of the coherence length from critical currents in the stoichiometric superconductor LiFeAs

M. Kończykowski, C. J. van der Beek, M. A. Tanatar +4

Miniature Hall-probe arrays were used to measure the critical current densities for the three main directions of vortex motion in the stoichiometric LiFeAs superconductor. These co…

Enhancement of vortex pinning in superconductor/ferromagnet bilayers via angled demagnetization

Marta Z. Cieplak, L. Y. Zhu, Z. Adamus +2

We use local and global magnetometry measurements to study the influence of magnetic domain width w on the domain-induced vortex pinning in superconducting/ferromagnetic bilayers,…

The valence electron photoemission spectrum of semiconductors: ab initio description of multiple satellites

Matteo Guzzo, Giovanna Lani, Francesco Sottile +7

The experimental valence band photoemission spectrum of semiconductors exhibits multiple satellites that cannot be described by the GW approximation for the self-energy in the fram…
