题 目: The beauty from the dirty -- recent challenges in Anderson localization

报告摘要: In the past fifteen years, an unprecedented degree of control reached in experiments with optical systems and ultracold atomic gases has triggered a "silent revolution" in studies of Anderson localization. In the first part of this talk, I shall present a brief review of the state of the art in localization. In the second part of this talk, I shall focus on the recent challenges in this field -- localization in open media. I will introduce recent experimental and theoretical studies showing that the interplay between wave interferences and the wave energy leakage at the boundaries may lead to very rich localization physics. Then, I will introduce an unconventional diffusive phenomenon—the local diffusion phenomenon—in open media.
