Band structure control in the altermagnetic candidate MnTe by temperature and strain

This study confirms the altermagnetic nature of hexagonal MnTe by demonstrating that its terahertz optical absorption, arising from spin-split bands, exhibits temperature-dependent behavior consistent with a ferromagnetic-like transition and strain-induced shifts that align with theoretical predictions of decreasing spin-splitting angles.

SAM Molecular Stacking with Heterogeneous Orientationfor High-Performance Perovskite Photovoltaics

This study demonstrates that thermal-evaporated self-assembled monolayers (eSAMs) with a unique vertical-to-horizontal molecular orientation gradient overcome the scalability and uniformity limitations of solution-processed SAMs, enabling high-efficiency perovskite photovoltaics with power conversion efficiencies up to 23.67%.

olLOSC: Unified and efficient density functional approximation to correct delocalization error in molecules and periodic materials

The paper introduces olLOSC, a unified and computationally efficient orbital-free density functional approximation that corrects delocalization errors in both molecules and periodic materials by calculating curvature via orbital-free electronic linear response, thereby enabling robust predictions of total energy, charge density, and band structure without the high cost of existing methods.

Molecular dynamics simulation of high slip flow of water confined between graphene nanochannels at experimentally accessible strain rates

This study demonstrates that the transient time correlation function (TTCF) method successfully enables the simulation of water slip flow in graphene nanochannels at experimentally accessible shear rates, yielding results consistent with equilibrium simulations and experiments where classical nonequilibrium molecular dynamics fails.
