Diamond formation from hydrocarbon mixtures in planets

Bingqing Cheng, Sebastien Hamel, Mandy Bethkenhagen

Hydrocarbon mixtures are extremely abundant in the Universe, and diamond formation from them can play a crucial role in shaping the interior structure and evolution of planets. Wit…

Same and interconvertible high-pressure ice phases

Aleks Reinhardt, Mandy Bethkenhagen, Federica Coppari +3

Most experimentally known high-pressure ice phases have a body-centred cubic (bcc) oxygen lattice. Our atomistic simulations show that, amongst these bcc ice phases, ices VII, VII'…

Dislocation-based strength model for high energy density conditions

Damian C. Swift, Kazem Alidoost, Ryan Austin +5

We derive a continuum-level plasticity model for polycrystalline materials in the high energy density regime, based on a single dislocation density and single mobility mechanism, w…

Properties of carbon up to 10 million kelvin from Kohn-Sham density functional theory molecular dynamics

Mandy Bethkenhagen, Abhiraj Sharma, Phanish Suryanarayana +3

Accurately modeling dense plasmas over wide ranging conditions of pressure and temperature is a grand challenge critically important to our understanding of stellar and planetary p…

Atom-in-jellium predictions of the shear modulus at high pressure

Damian C. Swift, Thomas Lockard, Sebastien Hamel +3

Atom-in-jellium calculations of the Einstein frequency in condensed matter and of the equation of state were used to predict the variation of shear modulus from zero pressure to ~$…

Predicting the phase behaviors of superionic water at planetary conditions

Bingqing Cheng, Mandy Bethkenhagen, Chris J. Pickard +1

Most water in the universe may be superionic, and its thermodynamic and transport properties are crucial for planetary science but difficult to probe experimentally or theoreticall…
