Navigating Order-(Dis)Order Family Trees via Group-Subgroup Transitions

This paper introduces a symmetry-based framework called "order-(dis)order family trees" to evaluate the true novelty of predicted crystal structures by identifying their relationships to known disordered parent phases, revealing that many seemingly novel ordered compounds are actually derived from existing disordered materials and highlighting the importance of this distinction for improving data-driven materials discovery.

How to quantify long-time rotational motion in molecular systems

This paper demonstrates that existing methods fail to quantify rotational motion in complex molecular systems like supercooled liquids and introduces a new empirical method that accurately captures the full spectrum of rotational dynamics from diffusive fluids to arrested solids, thereby resolving inconsistencies in the literature.

Self-consistent evaluation of the Berry connection for Wannier functions

This paper proposes a self-consistent interpolation scheme based on the matrix logarithm that significantly improves the accuracy of Berry connection evaluations and optical conductivity calculations by explicitly accounting for the matrix structure of overlap matrices and quantifying the impact of basis set incompleteness.

Effect of Mn Substitution on Superconductivity in PrFeAs(O,F): Role of Magnetic Impurities

This study demonstrates that substituting Fe with Mn in PrFeAs(O,F) acts as a potent magnetic impurity that suppresses superconductivity and induces insulating-like behavior, while also revealing the enhanced robustness of superconductivity in Pr-based systems compared to other rare-earth variants.

Neural surrogates for crystal growth dynamics with variable supersaturation: explicit vs. implicit conditioning

This paper compares two Convolutional Recurrent Neural Network architectures for simulating crystal growth under variable supersaturation, demonstrating that explicitly conditioning the network on the supersaturation parameter yields superior high-fidelity predictions compared to implicit inference via input mini-sequences, while both models exhibit strong scalability to larger domains and longer time sequences.
