    The Glassy Response of Double Torsion Oscillators in Solid 4He

    Single and double torsion oscillators have been used to measure the anomalous change in resonant frequency and accompanying dissipation in solid 4He. We present a glass description of the mechanical anomalies fou...

    Theory for the ultrafast dynamics of excited clusters: interplay between elementary excitations and atomic structure

    We present a theoretical study of the short-time relaxation of clusters in response to ultrafast excitations using femtosecond laser pulses. We analyze the excitation of different types of clusters (Hgn, Agn, Sin
