Microscopic investigation of enhanced Pauli paramagnetism in metallic PuC
R. Yamamoto, M. S. Cook, A. R. Altenhof +13
A combined study of the structural and electronic properties of polycrystalline PuC is reported based on x-ray diffraction, specific heat, magnetic susceptibility, ${}^{13}…
Adaptation of Wallace's Approach to the Specific Heat of Elemental Solids with Significant Intrinsic Anharmonicity, Particularly the Light Actinide Metals
Christopher A. Mizzi, W. Adam Phelan, Matthew S. Cook +6
The quasiharmonic approximation is the most common method for modeling the specific heat of solids; however, it fails to capture the effects of intrinsic anharmonicity. In this stu…
Designing Pu Intermetallics with First Principle Calculations
Matthew S. Cook, David C. Arellano, Derek V. Prada +3
We present the ab initio supported discovery of two new Pu based intermetallic compounds, PuNiSn and PuPtSn. Using density functional theory, the formation energies within the rele…
A noncollinear density functional theory ansatz for the phononic and thermodynamic properties of -Pu
Alexander R. Muñoz, W. Adam Phelan, Matthew S. Cook +6
Plutonium's phase diagram is host to complex structures and interactions that make the description of its ground state properties elusive. Using all-electron density functional the…
