The tetragonal to orthorhombic ferroelastic phase transition between rutile-and CaCl 2-type
SiO 2 at high pressures is studied using first-principles calculations and the Landau free …

The high-pressure phase diagram of Si O 2 has been calculated using density-functional
perturbation theory. We find that phase transitions of silica do not correspond to any …

The first-order diffusionless structural transition in Cu 67.64 Zn 16.71 Al 15.65 is
characterized by jerky propagation of phase fronts related to the appearance of avalanches …

CaIrO3-type MgSiO3 is the planet-forming silicate stable at pressures and temperatures
beyond those of Earth's core-mantle boundary. First-principles quasiharmonic free-energy …

Ultrahigh-pressure phase relationship of SiO2 silica in multimegabar pressure condition is
still quite unclear. Here, we report a theoretical prediction on a previously uncharacterized …

The stability of (Mg, Fe) SiO3 perovskite in the deep lower mantle has long been uncertain.
Recently, a phase transition from perovskite to postperovskite was discovered through a …

One of the most powerful approaches for understanding the 3‐D thermo‐chemical structure
of the lower mantle is to link tomographic models with mineral physics data. This is not …

Silica (SiO2) is an abundant material with a wide range of applications. Despite much
progress, the atomistic modelling of the different forms of silica has remained a challenge …
