    Abstract : The mechanical and acoustic anisotropy of media is a governing factor in the behaviour of multilayered systems including such media. The understanding of the mechanisms conditioning the dynamic behaviour of multilayered systems is of paramount importance. READ MORE

  4. 2. Vibrations in solids : From first principles lattice dynamics to high temperature phase stability

    Author : Nina Shulumba; Magnus Odén; Igor Abrikosov; Frank Mücklich; Matteo Calandra; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : In this thesis I introduce a new method for calculating the temperature dependent vibrational contribution to the free energy of a substitutionally disordered alloy that accounts for anharmonicity at high temperatures. This method exploits the underlying crystal symmetries in an alloy to make the calculations tractable. READ MORE
