First-principles calculations of equilibrium Mg isotope fractionations between garnet, clinopyroxene, orthopyroxene, and olivine: Implications for Mg isotope thermometry (2013, result): “The calculation details for some of minerals discussed in this study are very similar to previous studies (Karki et al., 2000; Li et al., 2007; Tsuchiya et al., 2004; Wu et al., 2008; Wu and Wentzcovitch, 2007; Yu et al., 2008, 2010, 2011; Yu and Wentzcovitch, 2006).”
Elasticity of post‐perovskite MgSiO3 (2004, methodology): “Its thermodynamic properties were obtained by means of quasiharmonic free energy calculations and the Clapeyron slope of the post-perovskite transition was shown to be 7.5 MPa/K [Tsuchiya et al., 2004].”
Postperovskite phase transition and its geophysical implications (2006, background): “The elastic properties were calculated both at 0 K [Tsuchiya et al., 2004b; Iitaka et al., 2004; Oganov and Ono, 2004] and high temperatures [Stackhouse et al., 2005; Wookey et al., 2005; Wentzcovitch et al., 2006].”
TX2019slab: A New P and S Tomography Model Incorporating Subducting Slabs (2019, background): “, 2013; Wu & Wentzcovitch, 2014) or the phase transition from bridgmanite to post‐perovskite (pPv; Murakami et al., 2004; Oganov & Ono, 2004; Tsuchiya et al., 2004).”
Nomenclature of the perovskite supergroup: A hierarchical system of classification based on crystal structure and composition (2017, background): “This phase is stable above 120 GPa at 2500 K (Murakami et al., 2004; Oganov and Ono, 2004; Tsuchiya et al., 2004).”
Radius and Structure Models of the First Super-Earth Planet (2006, background): “Below the ice layer, the pressure is 150 GPa, beyond the transition pressure between pv and ppv (P = 125GPa at T = 2750 K; Tsuchiya et al. 2004); therefore, the silicate mantle is made of ppv and fmw—perovskite and upper mantle silicate phases are absent.”
In situ observations of phase transition between perovskite and CaIrO3-type phase in MgSiO3 and pyrolitic mantle composition (2005, result): “Recently, this pioneering idea was confirmed by theoretical and experimental studies [27] [28] [29] [30].”
SP12RTS: a degree-12 model of shear- and compressional-wave velocity for Earth's mantle (2016, background): “…has a different composition (e.g. Su & Dziewonski 1997; Masters et al. 2000; Houser et al. 2008) or the presence of the post-perovskite (pPv) phase in the lower mantle (e.g. Iitaka et al. 2004; Murakami et al. 2004; Oganov & Ono 2004; Tsuchiya et al. 2004; Wookey et al. 2005; Davies et al. 2012).”
Post‐perovskite phase transition and mineral chemistry in the pyrolitic lowermost mantle (2005, background): “Phase transformation between MgPv and MgPP and the preferred orientation of MgPP may explain the seismic anomalies observed in this region [Iitaka et al., 2004; Oganov and Ono, 2004; Tsuchiya et al., 2004a].”
Rheology of the Earth's mantle: A historical review (2010, methodology): “In particular, so-called first-principle calculation has been applied to many properties including Gibbs free energy (stability of various phases) and elastic constants with great success (e.g., Karki et al., 2001; Stixrude et al., 1998; Tsuchiya et al., 2004).”
