Ground state properties that can be derived from total energy calculations — •Liviu Chioncel — Augsburg Center for Innovative Technologies, University of Augsburg, Germany

The temperature dependence of elastic constants for simple transition metal elements has been calculated using a combined first-principles and many-body theory. The thermal expansion has a normal linearly decreasing contribution to the elastic constant, while the electronic contribution is determined by the unique character of Coulomb correlations and may lead to anomalous temperature effects.
