4 p, 303.8 KB Metallic and semimetallic silicon <100> nanowires / Rurali, Riccardo (Université Paul Sabatier. Laboratoire Collisions, Agrégats, Réactivité) ; Lorente, N. (Université Paul Sabatier. Laboratoire Collisions, Agrégats, Réactivité) ; American Physical Society
Silicon nanowires grown along the <100> direction with a bulk Si core are studied with density-functional calculations. Two surface reconstructions prevail after exploration of a large fraction of the phase space of nanowire reconstructions. [...]

4 p, 915.2 KB Lattice solitons in quasicondensates / Ahufinger, Verònica (Universitat Autònoma de Barcelona. Departament de Física) ; Sanpera Trigueros, Anna (Universität Hannover. Institut für Theoretische Physik) ; American Physical Society
We analyze finite temperature effects in the generation of bright solitons in condensates in optical lattices. We show that even in the presence of strong phase fluctuations solitonic structures with a well defined phase profile can be created. [...]

(Institute for Nanotechnology (Enschede, Països Baixos)) ; van Hulst, Niek F. (Institute for Nanotechnology (Enschede, Països Baixos)) ; American Physical Society
We report the first experimental study of individual molecules with femtosecond time resolution using a novel ultrafast single-molecule pump-probe method. A wide range of relaxation times from below 100 up to 400 fs is found, revealing energy redistribution over different vibrational modes and phonon coupling to the nanoenvironment. [...]
