Extended X-ray absorption fine structure of dynamically-compressed copper up to 1 terapascal [PDF]

Nature Communications, 2023
Large laser facilities have recently enabled material characterization at the pressures of Earth and Super-Earth cores. However, the temperature of the compressed materials has been largely unknown, or solely relied on models and simulations, due to lack
