Iron spin crossover in ferropericlase and its effect on lower-mantle thermal conductivity
Alexander F. Goncharov, Irina Chuvashova, Eric Edmund +29
Thermal conductivity of Earths lower mantle controls heat transfer across the core-mantle boundary (CMB) and strongly influences mantle convection. We report direct measurements of…

Quantum Reorientational Excitations in the Raman Spectrum of Hydrogen
Philip Dalladay-Simpson, Eric Edmund, Huixin Hu +2
Low-frequency Raman peaks, below 250 cm-1, are observed in hydrogen between 2-174 GPa and 13-300 K. The origin of these features is attributed to reorientational transitions (Delta…
