Atomistic Modeling of the Negative Thermal Expansion in δ- Plutonium  Based on the Two-State Description

The δ phase  of plutonium with the fcc structure exhibits an unusual negative thermal expansion (NTE) over its narrow  temperature range of stability, 593–736 K. An accurate description  of the anomalous high-temperature volume effect of plutonium  goes beyond the current capability  of electronic-s...
