There is still a gap between ab initio methods and operative computational thermodynamics databases. In the past, a simplified approach introduced by the early works of Larry Kaufman, based on Miedema's Model, was employed to check the correctness of even the simplest binary systems. However, relating the two communities to Solid State Physics and Materials Science remains a challenge, as it has been for many years. Promising results from ab initio quantum mechanics molecular simulation packages like VASP are readily integrated in thermodynamic databases with approaches like Zentool. A relatively easy way to collect data for intermetallic compounds is now possible by using Open Quantum Materials Database. A series of papers focused on the concept of Zentropy has been proposed by prof. Z.K. Liu and his research group has been recently proposed
