Computational thermodynamics: Meaningful phase diagrams without experimental input? — •Sebastian Schwalbe1, Kai Trepte2, and Jens Kortus11TU Bergakademie Freiberg, Institute for Theoretical Physics, Germany — 2Central Michigan University, Department of Physics, USA

Ab-initio thermodynamic data sets, especially isobaric heat capacities, calculated within our new MD approach for lithium silicides [1,2] are presented. Further, a theoretical phase diagram is discussed, where the melting points are determined using a method based on the evaluation of diffusion behaviour. The key property, the so called diffusion coefficients, and the melting points themselves are compared with experimental data.
