DOI: 10.1103/physrevb.95.094115
Abstract: We start from the polynomic interatomic potentials introduced by Wojdel et al. [J. Phys. Condens. Matt. 25, 305401(2013)] and take advantage of one of their key features -- namely, the linear dependence of the energy… read more here.

DOI: 10.1103/physrevb.98.014301
Abstract: The thermal expansion behavior of metal fluorides can be tuned by choosing appropriate metal cation. We present ab-initio lattice dynamical studies on the metal fluorides (CaZrF6, MgZrF6 and SrZrF6) and identify the anharmonic phonon modes… read more here.
