Beryllium (Be) is an important material with wide applications ranging from aerospace components to X-ray equipments. Yet a precise understanding of its phase diagram remains elusive. We have investigated the phase stability of Be using a recently de

[1] We present first-principles results for elastic moduli (bulk, K, and shear, G) and acoustic velocities (compressional, VP, shear, VS, and bulk VΦ) of olivine (α) and wadsleyite (β) (Fex,Mg1 − x)2SiO4, at high pressure (P) and temperature (T)

In the emerging field of spin-electronics ideal ferromagnetic electron sources would not only possess a high degree of spin polarization, but would also offer control over the magnitude of this polarization. We demonstrate here that a simple scheme c

We predict a new pressure induced phase for silica via first principles variable-cell-shape molecular dynamics. The structure results from annealing a-quartz at pressures near a phonon instability. The mechanism which produces this new phase is simil

We discuss the behavior of two minerals of the same composition, Mg2SiO4 but different structures: forsterite and ringwoodite. Ab initio plane-wave pseudopotential results are discussed in terms of the full elastic constant tensors of these phases an

Introduction Silicate perovskites dominate the mineralogy of the Earth's lower mantle. Despite the progress made by in-situ high pressure/high temperature experiments in understanding their properties, these studies are still in their infancy and man
