报告摘要:
Waves, including electromagnetic, acoustic, and mechanical vibrations, are crucial in shaping the structure and dynamics of our world. In disordered systems, wave propagation is significantly hindered, impeding their mobility. Recent advancements in theoretical frameworks have introduced the concept of the 'localization landscape,' offering a promising approach to understanding wave localization in disordered media. This presentation will explore this innovative perspective, providing insights into localizations originating from disordered operators, and a new understanding of computing eigenpairs.
