“…Since no experimental values on these properties have been reported so far, we are unable to comment on them but our results will help the experimental workers to analyze their data in future. This study gets strong support from recent publications of our research group [24][25][26][27][28][29][30][31][32][33][34][35][36][37][38][39][40][41][42][43]. To conclude we can say that the present model SOE VTSM has successfully explained the phonon properties which include phonon dispersion curves variations of  D with temperature T and combined density of states.…”

“…In fact, the present model VTSM has revealed much better descriptions of dynamical properties of these compounds than those obtained by rigid shell model [26], deformation shell model [19], breathing shell model [20], extended three-body force shell model [1]. This study gets strong support from recent publications of our research group [32][33][34][35][36][37][38][39][40][41][42][43]. The induction of van der Waals interactions is much essential in the study of lattice dynamics of alkali halides crystals.…”

“…where s 11 , s 12 , s 44 are the components of elastic compliance tensor [44,45]. The components of elastic stiffness constants of NiO are C 11 ¼316 GPa, C 12 ¼56 GPa and C 44 ¼ 115 GPa [46]. The elastic compliance components (s ij ) can be obtained from the stiffness constants (c ij ) using the relations s11 ¼ (c 11 þc 12 )/(c 11 Àc 12 ) (c 11 þ2c 12 ); s 12 ¼ Àc 12 /(c 11 À c 12 )(c 11 þ2c 12 ); s 44 ¼1/c 44 [44,45].…”
