Sensitivity of stellar physics to the equation of state
D. C. Swift, T. Lockard, M. Bethkenhagen +3
The formation and evolution of stars depends on various physical aspects of stellar matter, including the equation of state (EOS) and transport properties. Although often dismissed…
Real-space formulation of the stress tensor for density functional theory: application to high temperature calculations
Abhiraj Sharma, Sebastien Hamel, Mandy Bethkenhagen +2
We present an accurate and efficient real-space formulation of the Hellmann-Feynman stress tensor for Kohn-Sham density functional theory (DFT). While applicable a…
High temperature ion-thermal behavior from average-atom calculations
Damian C. Swift, Mandy Bethkenhagen, Alfredo A. Correa +5
Atom-in-jellium calculations of the Einstein frequency were used to calculate the mean displacement of an ion over a wide range of compression and temperature. Expressed as a fract…
Atom-in-jellium equations of state in the high energy density regime
Damian C. Swift, Thomas Lockard, Richard G. Kraus +5
Recent path-integral Monte Carlo and quantum molecular dynamics simulations have shown that computationally efficient average-atom models can predict thermodynamic states in warm d…
