A quiet quantum revolution in Earth's deep interior
Renata Wentzcovitch, Laura Cobden, Christine Houser +2
The Earth's lower mantle hosts a subtle but pervasive quantum phenomenon: the pressure-induced spin crossover of iron in its dominant minerals, bridgmanite and ferropericlase. In t…
Full-waveform tomography reveals iron spin crossover in Earth lower mantle
Laura Cobden, Jingyi Zhuang, Wenjie Lei +3
Joint interpretation of bulk and shear wave speeds constrains the chemistry of the deep mantle. At all depths, the diversity of wave speeds cannot be explained by an isochemical ma…
Thermodynamics of spin crossover in ferropericlase: an improved LDA+ calculation
Yang Sun, Jingyi Zhuang, Renata M. Wentzcovitch
We present LDA+ calculations of high-spin (HS) and low-spin (LS) states in ferropericlase (fp) with an iron concentration of 18.75. The Hubbard parameter is determi…
