The Earth's magnetic field is powered by energy supplied by the slow cooling and freezing
of the liquid iron core. Efforts to determine the thermal and chemical history of the core have …

We present an accurate machine learning (ML) model for atomistic simulations of carbon,
constructed using the Gaussian approximation potential (GAP) methodology. The potential …

This paper provides the state-of-the-art discussion of major aspects of the composition and
evolution of the Earth's core. A comparison of experimentally-derived density of Fe with …

Matter at extreme temperatures and pressures—commonly known as warm dense matter
(WDM)—is ubiquitous throughout our Universe and occurs in astrophysical objects such as …

Earth continuously generates a dipole magnetic field in its convecting liquid outer core by a
self-sustained dynamo action. Metallic iron is a dominant component of the outer core, so its …

We measured the electrical resistivity of iron and iron-silicon alloy to 100 GPa. The resistivity
of iron was also calculated to core pressures. Combined with the first geophysical model …

Modern observations of the geomagnetic field reveal fluctuations,, with a dominant period of
about 60 years. These fluctuations are probably a result of waves in the liquid core, although …

Light elements in Earth's core play a key role in driving convection and influencing
geodynamics, both of which are crucial to the geodynamo. However, the thermal transport …

We measure the electrical resistivity of hcp iron up to∼ 170 GPa and∼ 3000 K using a four-
probe van der Pauw method coupled with homogeneous flattop laser heating in a DAC, and …

Radiogenic heat production is fundamental to the energy budget of planets. Roughly half of
the heat that Earth loses through its surface today comes from the three long-lived, heat …
