On May 24, 2022, Professor Zhang Jie's research group from the Institute of Natural Sciences, School of Physics and Astronomy, Shanghai Jiao Tong University, in collaboration with researcher Jin Yuliang from the Institute of Theoretical Physics, Chinese Academy of Sciences, published a paper entitled " Experimental observations " in the Proceedings of the National Academy of Sciences (PNA.
A disordered system composed of photoelastic particles and its visualized force chain network
Only a few months ago, the 2021 Nobel Prize in Physics was awarded to the field of complex systems for Professor Giorgio Parisi for his "discovery between disorder and fluctuation in physical systems ranging from atomic to planetary scale.
On the other hand, before replica theory gave exact values for the two exponents, Matthieu Wyart and his collaborators, through a completely independent method—the edge mechanical stability analysis—suggested that the two exponents should satisfy relationsh.
The importance of this research result lies in the direct verification of the predictions given by the above two theoretical analyses through experimen.
The first author of this work is Wang Yinqiao, a .
