The postperovskite transition in Fe- and Al-bearing bridgmanite: effects on seismic observables
Juan J. Valencia-Cardona, Renata M. Wentzcovitch, Jingyi Zhuang +2
The primary phase of the Earth's lower mantle, (Al, Fe)-bearing bridgmanite, transitions to the postperovskite (PPv) phase at Earth's deep mantle conditions. Despite extensive expe…
cij: A Python code for quasiharmonic thermoelasticity
Chenxing Luo, Xin Deng, Wenzhong Wang +3
The Wu-Wentzcovitch semi-analytical method (SAM) is a concise and predictive formalism to calculate the high-pressure and high-temperature (high-PT) thermoelastic tensor (Cij) of c…
Bullen's parameter as a seismic observable for spin crossovers in the lower mantle
Juan J. Valencia-Cardona, Quentin Williams, Gaurav Shukla +1
Elastic anomalies produced by the spin crossover in ferropericlase have been documented by both first principles calculations and high pressure-temperature experiments. The predict…
Thermoelasticity of Fe- and Al-bearing bridgmanite
Gaurav Shukla, Matteo Cococcioni, Renata M. Wentzcovitch
We report \textit{ab initio} (LDA + U) calculations of thermoelastic properties of ferric iron (Fe)- and aluminum (Al)-bearing bridgmanite (MgSiO perovskite), the…
Iron spin crossover and its influence on post-perovskite transitions in MgSiO and MgGeO
Gaurav Shukla, Mehmet Topsakal, Renata M. Wentzcovitch
MgGeO-perovskite is known to be a low-pressure analog of MgSiO-perovskite in many respects, but especially in regard to the post-perovskite transition. As such, investigati…
Thermoelasticity of Fe2+-bearing bridgmanite
Gaurav Shukla, Zhongqing Wu, Han Hsu +3
We present LDA+U calculations of high temperature elastic properties of bridgmanite with composition (MgFe)SiO for . Results of elastic mo…
