On October 23, the School of Physics and Electronic Science held the 324th Lakeshore Forum in F347, Wenlan Building. The exchange meeting was sponsored by the School Youth League Committee and the Youth League Committee of the School of Physics and Electronic Science. Professor Shang Baoshuang, an outstanding young scholar of Songshan Lake Materials Laboratory, served as the keynote speaker.

Shang Baoshuang mainly focused on "the morphology and characteristics of amorphous potential energy surface" as the theme of the lecture. He first introduced the basic concept and formation process of amorphous solids. Amorphous solids are generally formed by the rapid cooling of the liquid to avoid crystallization, and this process is accompanied by obvious kinetic changes. The relaxation time of the system - that is, the time it takes to return from a state to equilibrium - undergoes a huge range, stretching from the extremely short 1 picosecond (ps) to more than 100 seconds, spanning more than a dozen orders of magnitude. This dynamic behavior shows three unique characteristics of non-Arrhenius, non-exponential and nonlinear, which is the key to understanding the nature of amorphous materials.

Then, Shang Bao-shuang takes the non-exponential property of kinetic relaxation as the starting point to deeply demonstrate the relationship between this non-exponential property and the morphology of potential energy surface. He revealed the topological structure and characteristics of the amorphous potential energy surface morphology by statistical means, and discussed how to understand and regulate the potential energy surface by using deformation and relaxation. Shang Baoshuang's explanation not only allows the audience to have a deeper understanding of the dynamic behavior of amorphous materials, but also provides a useful reference for students to understand their nature and regulate the properties of amorphous materials.

Finally, Shang Baoshuang shared his understanding in the research process in the field of amorphous materials, and encouraged students to make full use of their university years, stimulate their own potential, have the courage to innovate and research, and explore and cultivate their own advantages.

The successful holding of this event provided a platform for teachers and students to exchange academic ideas and discuss scientific research issues, and also stimulated students' interest and enthusiasm for scientific research, laying a foundation for the school to carry out relevant scientific research work, and helping the school to carry out high-quality development and high-quality student training in 2024.
