Assoc. Prof. Tong Hua’s Team Elucidates Origin of Solidity of Amorphous Materials

October 12, 2020      Author:

Recently, the research team led by Associate Professor Tong Hua from School of Physics and Astronomy, SJTU published their research titled "Emergent solidity of amorphous materials as a consequence of mechanical self-organisation" in Nature Communications. In this research, they elucidate how the solidity of amorphous solids stems from mechanical self-organisation under nonequilibrium and anharmonic fluctuations, which is a great breakthrough on the origin of the solidity of amorphous materials at finite temperatures. 

The research team, together with their partners, focused on the transition of mechanical properties in liquid forming amorphous solids upon cooling. Based on large-scale computer simulation, they found that nonequilibrium glass transition is inseparable from the long-range stress correlation. The study sheds new light on the very nature of amorphous solids from the mechanical perspective.

The first author is tenure-track Associate Professor Tong Hua from School of Physics and Astronomy. Shiladitya Sengupta and Prof. Hajime Tanaka from The University of Tokyo also participated in the research.
