Radial gradient of superionic hydrogen in Earth's inner core
Zepeng Wu, Liangrui Wei, Chen Gao +3
Hydrogen is considered a key light element in Earth's core, yet the thermodynamics of its superionic phase and its distribution in the inner core remain unclear. Here, we compute a…

Ab initio superionic-liquid phase diagram of Fe1-xOx under Earth's inner core conditions
Zepeng Wu, Chen Gao, Feng Zhang +4
The superionic state is a phase of matter in which liquid-like ionic mobility coexists with a solid crystalline lattice. Recently identified in Earth's inner core (IC), this state…

Understanding the two-step nucleation of iron at Earth's inner core conditions: a comparative molecular dynamics study
Chen Gao, Kai-Ming Ho, Renata M. Wentzcovitch +1
Metastable phases can lead to multistep nucleation processes, influencing the liquid-to-solid transition in various systems. In this study, we investigate the homogeneous nucleatio…
