Force Field-Agnostic Phase Classification of Zeolitic Imidazolate Framework Polymorphs

This paper demonstrates that neural network classifiers trained on diverse force fields and descriptors can accurately and agnostically identify Zeolitic Imidazolate Framework (ZIF) polymorphs during molecular dynamics simulations, thereby enabling the detailed mechanistic study of phase transitions like ZIF-4-cp to ZIF-4-cp-II.

The hidden ferroelectric chiral ground state of silver niobate

First-principles calculations reveal that silver niobate's true thermodynamic ground state is a previously overlooked, chiral rhombohedral ferroelectric phase with R3R3 symmetry, which exhibits significant natural optical activity and may explain the ongoing controversy regarding its low-temperature structure due to kinetic limitations hindering its experimental observation.

Pressure-Induced Superconducting-like Transition in the d\it d-wave Altermagnet Candidate CsV2_2Se2_2O

This study demonstrates that applying hydrostatic pressure to the dd-wave altermagnet candidate CsV2_2Se2_2O suppresses its weakly insulating parent state and induces a reproducible, field-sensitive superconducting-like transition below 3 K, suggesting a potential link between altermagnetism and unconventional superconductivity.

High-temperature superconductivity in Nd0.85_{0.85}Sr0.15_{0.15}NiO2_2 membranes under pressure

By incorporating freestanding infinite-layer Nd0.85_{0.85}Sr0.15_{0.15}NiO2_2 membranes into a diamond anvil cell, researchers demonstrated that hydrostatic pressure induces a strong, linear increase in superconducting transition temperature up to ~90 GPa without saturation, reaching near liquid nitrogen temperatures.
