Melting curve and Hugoniot of molybdenum up to 400 GPa by ab initio simulations
We report ab initio calculations of the melting curve and Hugoniot of molybdenum for the pressure range 0 − 400 GPa, using density functional theory (DFT) in the projector augmented wave (PAW) implementation. We use the “reference coexistence” technique to overcome uncertainties inherent in earlier DFT calculations of the melting curve of Mo. Our calculated melting curve agrees well with experi...
متن کاملA synchrotron Mössbauer spectroscopy study of (Mg,Fe)SiO3 perovskite up to 120 GPa
The electronic environment of the Fe nuclei in two silicate perovskite samples, Fe0.05Mg0.95SiO3 (Pv05) and Fe0.1Mg0.9SiO3 (Pv10), have been measured to 120 GPa and 75 GPa, respectively, at room temperature using diamond anvil cells and synchrotron Mössbauer spectroscopy (SMS). Such investigations of extremely small and dilute Fe-bearing samples have become possible through the development of S...
متن کاملEquation of state measurements in liquid deuterium to 70 GPa.
Using intense magnetic pressure, a method was developed to launch flyer plates to velocities in excess of 20 km/s. This technique was used to perform plate-impact, shock wave experiments on cryogenic liquid deuterium ( L-D(2)) to examine its high-pressure equation of state. Using an impedance matching method, Hugoniot measurements were obtained in the pressure range of 30-70 GPa. The results of...
متن کاملPath integral monte carlo calculation of the deuterium hugoniot
Restricted path integral Monte Carlo simulations have been used to calculate the equilibrium properties of deuterium for two densities: 0.674 and 0.838 g cm(-3) ( r(s) = 2.00 and 1.86) in the temperature range of 10(5)</=T</=10(6) K. We carefully assess size effects and dependence on the time step of the path integral. Further, we compare the results obtained with a free particle nodal restrict...
متن کاملCalculation of Shock Hugoniot Curves of Precompressed Liquid Deuterium
Path integral Monte Carlo simulations have been used to study deuterium at high pressure and temperature. The equation of state has been derived in the temperature and density region of 10 000 ≤ T ≤ 1 000 000K and 0.6 ≤ ρ ≤ 2.5 g cm. A series of shock Hugoniot curves is computed for different initial compressions in order to compare with current and future shock wave experiments using liquid de...
