The Potential Energy Landscape Perspective on Plasticity and Flow - Part I

Explore recent advances in understanding microscopic stress autocorrelation in amorphous solids through this comprehensive lecture. Delve into the discovery of asymptotic power-law tails in stress correlations and their connection to material isotropy, mechanical balance, and stress fluctuation normality. Compare the behavior of fragile (Lennard-Jones) and strong (silica) glasses, examining the transient oscillatory exponential decay in strong glasses due to near hyperuniformity of local stress fluctuations. Investigate the importance of coarse-graining scale in stress observation and its potential as a key discriminating feature between fragile and strong glasses. Gain insights from rigorous proofs and recent research findings, supported by references to relevant studies in the field of glass physics and material science.
