    <title language="eng">Coherent acoustic and optical phonons in laser-excited solids studied by ultrafast time-resolved X-ray diffraction</title>
    <abstract language="eng">We apply ultrafast time‐resolved X‐ray diffraction to directly study coherent acoustic and optical phonons in laser‐excited materials. In Au the ps acoustic response has been investigated with the particular goal to clarify the interplay of electronic and thermal pressure contributions. In Bi the extreme softening of the coherently excited A 1 g optical phonon presents strong indication that upon intense laser‐excitation the Peierls‐transition which determines the equilibrium structure of Bi can be reversed. In FeRh we studied the lattice response after a fast laser‐induced anti‐ferromagnetic to ferromagnetic phase transition.</abstract>

    <title language="eng">Transient reversal of a Peierls-transition: Extreme phonon softening in laser-excited Bismuth</title>
    <abstract language="eng">Laser-excited coherent optical phonons in Bismuth were investigated using time-resolved X-ray diffraction. The observed extreme softening of the excited A1g-mode presents strong indication that the Peierls-distortion defining the equilibrium structure of Bismuth is transiently reversed.</abstract>
