Structure and Phase Transitions of Metastable Hexagonal Uranium Thin Films

Rebecca Nicholls, Chris Bell, Johann Bouchet +2

We report a simple technique for the synthesis of uniaxially textured, metastable hexagonal close-packed-like uranium thin films with thicknesses between 175-2800 Å. The initial st…

Decaying shock studies of phase transitions in MgOSiO2 systems: implications for the Super-Earths interiors

R. M. Bolis, G. Morard, T. Vinci +15

We report an experimental study of the phase diagrams of periclase (MgO), enstatite (MgSiO3) and forsterite (Mg2SiO4) at high pressures. We investigated with laser driven decaying…

Melting of iron close to Earth's inner core boundary conditions and beyond

M. Harmand, A. Ravasio, S. Mazevet +23

Several important geophysical features such as heat flux at the Core-Mantle Boundary or geodynamo production are intimately related with the temperature profile in the Earth's core…

The malleability of uranium: manipulating the charge-density wave in epitaxial films

R. Springell, R. C. C. Ward, J. Bouchet +6

We report x-ray synchrotron experiments on epitaxial films of uranium, deposited on niobium and tungsten seed layers. Despite similar lattice parameters for these refractory metals…

Understanding the complex phase diagram of uranium: the role of electron-phonon coupling

S. Raymond, J. Bouchet, G. H. Lander +8

We report an experimental determination of the dispersion of the soft phonon mode along [1,0,0] in uranium as a function of pressure. The energies of these phonons increase rapidly…

Ab-initio Gutzwiller method: first application to Plutonium

J. P. Julien, Johann Bouchet

Except for small molecules, it is impossible to solve many electrons systems without imposing severe approximations. If the configuration interaction approaches (CI) or Coupled Clu…
