    • To describe the thermodynamics of solids one must, in principle, also compute the entropy, consider the electronic, magnetic and lattice (vibrational) contributions in the Gibbs free energy. The first two contributions are generally small and can be neglected in the paramagnetic phase of a wide-band insulator, whereas the lattice entropy may have an influence on a structural phase transition. To estimate its contribution would require to perform molecular dynamics calculations for a correlated system. This is a very demanding project which we plan to do in the future.
