Pressure has long been recognized as a fundamental thermodynamic variable but its
application was previously limited by the available pressure vessels and probes. The …

Pressure profoundly alters all states of matter. The symbiotic development of ultrahigh-
pressure diamond anvil cells, to compress samples to sustainable multi-megabar pressures; …

Observations of seismic anisotropy yield some of the most direct constraints available on
both past and present-day deformation in the Earth's mantle. Insight into the character of …

We present a 3-D radially anisotropic S velocity model of the whole mantle (SAW642AN),
obtained using a large three component surface and body waveform data set and an …

Measurements of the splitting or birefringence of seismic shear waves that have passed
through the Earth's mantle yield constraints on the strength and geometry of elastic …

In this section the contribution of CPO to seismic anisotropy in the deep Earth with cases of
olivine and the role of melt is illustrated. The CPO in rocks of upper-mantle origin is now well …

The study of structure, thermodynamic state, equation of state (EOS) and transport properties
of warm dense matter (WDM) has become one of the key aspects of laboratory astrophysics …

Recently we are witnessing the boom of high-pressure science and technology from a small
niche field to becoming a major dimension in physical sciences. One of the most important …

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 …

Seismic anisotropy has been found in many regions of the Earth's interior. Its presence in the
Earth's crust has been known since the 19th century, and is due in part to the alignment of …
