Elasticity of polycrystalline davemaoite constrains its grain size in the lower mantle
Peiyu Zhang, Liang Yuan, Rong Huang +3
Earth's lower mantle hosts large low shear-velocity provinces (LLSVPs) beneath Africa and the Pacific, but their origin remains debated. Davemaoite, a major lower-mantle mineral, h…

A Thermodynamic-Limit Pinning Criterion for Two-Dimensional Structural Superlubricity
Li Wang, Yunjie Ye
Incommensurability and elastic reconstruction do not by themselves define a structurally superlubric phase. We define fully sliding and pinned zero-temperature phases by $\limsup_{…

Rao-Blackwell Gradient Estimators for Equivariant Denoising Diffusion
Vinh Tong, Hoang Trung-Dung, Anji Liu +2
In domains such as molecular and protein generation, physical systems exhibit inherent symmetries that are critical to model. Two main strategies have emerged for learning invarian…
