A Jacobian‐Free Newton‐Krylov Method for Cell‐Centred Finite Volume Solid Mechanics

International Journal for Numerical Methods in Engineering, Volume 127, Issue 3, 15 February 2026.
ABSTRACT This study proposes a Jacobian‐free Newton‐Krylov approach for finite‐volume solid mechanics. Traditional Newton‐based approaches require explicit Jacobian matrix formation and storage, which can be computationally expensive and memory‐intensive.

Self‐Trapped Hole Migration and Defect‐Mediated Thermal Quenching of Luminescence in α‐ and β‐Ga2O3

Advanced Functional Materials, Volume 36, Issue 13, 12 February 2026.
Temperature‐dependent photoluminescence and first‐principles calculations reveal self‐trapped hole migration as the microscopic origin of thermal quenching in α‐ and β‐Ga2O3. The low migration barrier in α‐Ga2O3 enables defect trapping and enhances blue luminescence, while the higher barrier in β‐Ga2O3 preserves ultraviolet emission at elevated ...

Structural Colors from Ultrathin Lignin Films

Advanced Optical Materials, Volume 14, Issue 5, 2 February 2026.
Thickness‐dependent structural colors in ultrathin lignin films generate a full visible palette, tuned simply by solution concentration and spin speed. Abstract Structural colors offer a sustainable alternative to toxic pigments and dyes, yet their realization from lignin, the most abundant aromatic biopolymer, has remained elusive.

On the Modeling of Irreversibility by Relaxator Liouville Dynamics

Annalen der Physik, Volume 538, Issue 2, February 2026.
A general approach to modeling irreversibility starting from microscopic reversibility is presented. A relaxator that breaks reversibility condenses in the Liouville operator of the relevant degrees of freedom. The irreversible relaxator Liouville equation contains memory effects and initial correlations of all degrees of freedom. Stationary states are

Efficient Dynamics: Reduced‐Order Modeling of the Time‐Dependent Schrödinger Equation

Advanced Physics Research, Volume 5, Issue 2, February 2026.
Reduced‐order modeling (ROM) approaches for the time‐dependent Schrödinger equation are investigated, highlighting their ability to simulate quantum dynamics efficiently. Proper Orthogonal Decomposition, Dynamic Mode Decomposition, and Reduced Basis Methods are compared across canonical systems and extended to higher dimensions.
