Equation of state, phonons, and lattice stability of ultra-fast warm dense matter
Louis Harbour, Chandre M. Dharma-wardana, Dennis D. Klug +1
Using the two-temperature model for ultrafast matter (UFM), we compare the equation of state, pair-distribution functions , and phonons using the neutral pseudoatom (NPA) mod…
Pair potentials for warm dense matter and their application to x-ray Thomson scattering in aluminum and beryllium
Louis Harbour, M. W. Chandre Dharma-wardana, Dennis D. Klug +1
Ultrafast laser experiments yield increasingly reliable data on warm dense matter, but their interpretation requires theoretical models. We employ an efficient density functional n…
A critical assessment of models of pair-interactions and screening used in analyzing recent warm-dense matter (WDM) experiments
L. Harbour, M. W. C. Dharma-wardana, D. D. Klug +1
Ultra-fast laser experiments yield increasingly reliable data on warm-dense matter (WDM), but rely on entrenched simplistic theoretical models. We re-analyze two topical experiment…
Vibrational Properties of Nanoscale Materials: From Nanoparticles to Nanocrystalline Materials
R. Meyer, L. J. Lewis, S. Prakash +1
The vibrational density of states (VDOS) of nanoclusters and nanocrystalline materials are derived from molecular-dynamics simulations using empirical tight-binding potentials. The…
Stacking-fault energies for Ag, Cu, and Ni from empirical tight-binding potentials
R. Meyer, L. J. Lewis
The intrinsic stacking-fault energies and free energies for Ag, Cu, and Ni are derived from molecular-dynamics simulations using the empirical tight-binding potentials of Cleri and…
Optical properties of structurally-relaxed Si/SiO superlattices: the role of bonding at interfaces
Pierre Carrier, Laurent J. Lewis, M. W. Chandre Dharma-wardana
We have constructed microscopic, structurally-relaxed atomistic models of Si/SiO superlattices. The structural distortion and oxidation-state characteristics of the interface S…
