The thermal conductivities of materials are extremely important for many practical
applications, such as in understanding the thermal balance and history of the Earth, energy …

The Earth can be viewed as a massive heat engine, with various energy sources and sinks.
Insights into its evolution can be obtained by quantifying the various energy contributions in …

The fourth edition of Physics of the Earth maintains the original philosophy of this classic
graduate textbook on fundamental solid earth geophysics, while being completely revised …

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

We have critically reviewed and discussed currently available information regarding the spin
and valence states of iron in lower mantle minerals and the associated effects of the spin …

Using density functional theory plus Hubbard U calculations, we show that the ground state
of (Mg, Fe)(Si, Fe) O 3 perovskite, the major mineral phase in Earth's lower mantle, has high …

Mineral properties in Earth's lower mantle are affected by iron electronic states, but
representative pressures and temperatures have not yet been probed. Spin states of iron in …

We combine first-principles calculations of forces with the direct nonequilibrium molecular
dynamics method to determine the lattice thermal conductivity k of periclase (MgO) up to …

Thermal conductivity of the Earth's lower mantle greatly impacts the mantle convection style
and affects the heat conduction from the core to the mantle. Direct laboratory measurement …

Changes in the electronic configuration of iron at high pressures toward a spin-paired state
within host minerals ferropericlase and silicate perovskite may directly influence the seismic …
