Pressure-induced thermal expansion anomalies in dhcp iron hydride associated with magnetoelastic coupling

Yuichiro Mori, Katsutoshi Aoki, Hiroyuki Kagi, Masahiro Takano et autres

Iron hydride with a double hexagonal close-packed structure (dhcp-FeHx) undergoes a ferromagnetic-paramagnetic transition without changing its crystal structure. Despite its relevance to metal-hydrogen interactions and magnetically driven elasticity, the extensive investigation of this phase is almost limited to room temperature. Here, we …

Suppression of Metallic Transport in Nitrogen-rich Two-Dimensional Transition Metal Nitrides

Hongze Gao, Da Zhou, Nguyen Tuan Hung, Chengdong Wang et autres

The recent experimental realization of two-dimensional (2D) transition metal nitrides (TMNs, e.g., Mo5N6, δ-MoN, and W5N6) opens new opportunities for exploring their fundamental physical properties at the two-dimensional limit. In this work, we propose a unified picture of transport phenomena in the …

Efficient Tail-Aware Generative Optimization via Flow Model Fine-Tuning

Zifan Ivan Wang, Riccardo De Santi, Xiaoyu Mo, Michael M. Zavlanos et autres

Fine-tuning pre-trained diffusion and flow models to optimize downstream utilities is central to real-world deployment. Existing entropy-regularized methods primarily maximize expected reward, providing no mechanism to shape tail behavior. However, tail control is often essential: the lower tail determines reliability by limiting …
