I, Haruhiko Dekura, from the Theoretical Mineral Physics Group (TMPG) at the Geophysical Research Center, Ehime University, have been vigorously advancing first-principles research on the \u03ba<sub>lat<\/sub>&nbsp;of Earth\u2019s minerals for over a decade in collaboration with Prof. Taku Tsuchiya (Director). Based on our extensive research experiences, we were invited to contribute a review paper on the recent progress in the study of \u03ba<sub>lat<\/sub>&nbsp;of LM minerals. In this paper, we provide a comprehensive review of theoretical and experimental studies on the major LM minerals (MgO, MgSiO\u2083 bridgmanite (Brg) and post-perovskite (PPv)), and include a comparison of various theoretical calculation methods alongside experimental findings. We also give an overview of ab initio anharmonic lattice dynamics techniques developed in TMPG to compute \u03ba<sub>lat<\/sub>. The paper highlights the relative magnitude of \u03ba<sub>lat<\/sub>&nbsp;among these end-member LM phases (Fig. 1) and the effects of iron solid solution on the \u03ba<sub>lat<\/sub>. Previously under-discussed effects such as isotopic mass difference and higher-order crystal anharmonicity are also summarized in detail. Additionally, we describe current problems and future research directions for the thermal transport properties of the deep mantle (Haruhiko Dekura).<\/p>\n\n\n\n<p>Recent progress in the study on phonon heat transport property of Earth\u2019s lower mantle minerals.
