High Pressure-Temperature Phase Diagrams and Free Energies from First Principles
Stanimir Bonev | 23-ERD-042
Executive Summary
We are developing an infrastructure for the computation of liquid entropies, predicting finite-temperature crystal structures and performing dynamical simulations with a desired level of exchange approximation. It will overcome critical limitations for computating phase diagrams and have immediate impact on the design/interpretation of high-pressure experiments and equation of state modelling in support of the stockpile stewardship national security mission.
