Over the past decade, semiconductor materials subjected to photothermal, optoelectronic, and magnetoacoustic excitations have become increasingly important due to their critical role in modern electronic, photonic, and emerging quantum devices. The interaction between thermal, elastic, electrical, and acoustic fields strongly affects wave propagation, stability, and energy transport in these materials. Recent advances in computational modeling, numerical simulation, and experimental measurement techniques have provided powerful tools for understanding and controlling these coupled multiphysical phenomena.

There is significant progress in developing analytical, numerical, and stochastic approaches for modeling semiconductor behavior under complex excitations. Techniques such as stability and eigenvalue analysis, perturbation methods, Monte Carlo simulations, and multiphysics numerical schemes have shown strong potential in predicting material response and uncertainty behavior. At the same time, improved experimental protocols and signal-processing methods have enhanced the validation and reliability of theoretical models.

Given these advances, the current moment is ideal for a focused experimental and computational collection of research. This collection welcomes submissions in the following categories: original research articles, methodology articles, and review articles that emphasize reproducible methods and validated modeling frameworks.

Topics of interest include, but are not limited to:

• Experimental methods for photo-thermal, opto-electronic, and magneto-acoustic characterization of semiconductor materials
• Numerical and analytical techniques for coupled thermoelastic, photoacoustic, and semiconductor models
• Stability analysis, eigenvalue methods, and perturbation approaches in multiphysics systems
• Stochastic modeling and Monte Carlo simulations for uncertainty quantification in semiconductor materials
• Wave propagation, transport phenomena, and multiphysical field coupling in advanced materials
• Visualization, signal processing, and data analysis methods for multiphysics experimental measurements

This collection aims to standardize and enhance the reproducibility and reliability of experimental and computational workflows in semiconductor and quantum-related material research. It seeks to bridge applied mathematics, computational physics, and experimental methodologies, supporting the development of accurate, efficient, and physically consistent methods for studying complex coupled-field phenomena in advanced semiconductor systems.
