TY - JOUR AU - Ropo, Matti AU - Akola, Jaakko AU - Jones, Robert O. TI - Collective excitations and viscosity in liquid Bi JO - The journal of chemical physics VL - 145 IS - 18 SN - 1089-7690 CY - Melville, NY PB - American Institute of Physics M1 - FZJ-2016-05923 SP - 184502 PY - 2016 AB - The analysis of extensive density functional/molecular dynamics simulations (over 500 atoms, up to 100 ps) of liquid bismuth at four temperatures between 573 K and 1023 K has provided details of the dynamical structure factors, the dispersion of longitudinal and transverse collective modes, and related properties (power spectrum, viscosity, and sound velocity). Agreement with available inelastic x-ray and neutron scattering data and with previous simulations is generally very good. The results show that density functional/molecular dynamics simulations can give dynamical information of good quality without the use of fitting functions, even at long wavelengths.
