Quantum phase transition detected on a global scale deep inside the Earth

A multidisciplinary team of materials physicists and geophysicists combine theoretical predictions, simulations, and seismic tomography to find spin transition in the Earth's mantle. Their findings will improve understanding of the Earth's interior, and help elucidate the impact of this phenomenon on tectonic events including volcanic eruptions and earthquakes.
