Abstract
ABSTRACTThe present article deals with the study of the dynamical behaviour of the heavily dense liquid alkali metals using velocity autocorrelation function (VACF) and power spectrum . The extended Brownian motion equation is used to generate VACF for liquid metals in the present work. The presently obtained results are compared with those generated by the molecular dynamical study (MD) as well as other theoretical models. The model potential given by Fiolhais et al. is used for the calculation of the VACF. The screening effect over the bare ion potential results is estimated with the help of Hartree (H) dielectric function. The exchange and correlation effects are calculated with the functions given by Sarkar et al. (S) and Ichimaru–Utsumi (IU).
