The thermal properties of bulk copper are investigated by performing ab initio DFT and DFPT calculations and using the quasiharmonic approximation for the free energy. Using both the LDA and the GGA for the exchangecorrelation potential, we compute the temperature dependence of the lattice constant, coefficient of thermal expansion, bulk modulus, pressure derivative of the bulk modulus, phonon ...
The yielding transition of amorphous materials is studied with a two-dimensional Hamiltonian model that allows both shear and volume deformations. investigated as function the relative value bulk modulus $B$ respect to $\mu$. When ratio $B/\mu$ small enough, becomes discontinuous, yet reversible. If system driven at constant strain rate in coexistence region, spatially localized band observed w...
The presence of hydrogen can affect elastic properties and seismic velocities of minerals in the Earth's upper mantle. In this study, the secondorder elastic constants of hydrous wadsleyites containing 0.37, 0.84, and 1.66 wt.% H2O were determined by Brillouin scattering at ambient conditions. Measurements were performed on at least three independent crystal planes for each composition. The agg...
