    • Ab initio calculations of elastic properties of compressed Pt 
      Menéndez Proupin, Eduardo; Singh, Anil K. (2007)
      First-principles calculations of the equation of state and single-crystal elastic constants of platinum have been carried out to 650 GPa using density-functional theory (DFT). The present equation of state deduced at 300 ...
    • Elastic properties of the bcc structure of bismuth at high pressure 
      Gutiérrez Gallardo, Gonzalo; Menéndez Proupin, Eduardo; Singh, Anil K. (AMER INST PHYSICS, 2006-05-15)
      First-principles calculations of the single-crystal elastic constants of the body-centered cubic phase of bismuth are carried out in the pressure range of 31-191 GPa. The calculations are performed in the framework of ...
    • Nonhydrostatic compression of bismuth to 222 GPa: Some constraints on elasticity of the bcc-phase 
      Singh, Anil K.; Menéndez Proupin, Eduardo; Gutiérrez, G.; Akahama, Yuichi; Kawamura, H. (PERGAMON-ELSEVIER SCIENCE LTD, 2006-10)
      Polycrystalline bismuth sample was compressed in a diamond anvil cell and X-ray diffraction patterns from the body centered cubic phase of bismuth (bcc-Bi) recorded in the pressure range 12-222 GPa. The analysis of diffraction ...
