Electronic Structures of CaSiO3 Glass under Megabar Pressures: Ca L 2,3-Edge and O K -Edge X-ray Raman Scattering

The extreme densification of silicate glasses above 100 GPa reorganizes chemical bonding around both the oxygen network and the network-modifying cations. These responses, however, have largely been probed separately, leaving their coupling during extreme densification unresolved. Here, we report the first O K-edge a...
