Relaxation of quenched structural glasses: descent in a stiffening caging potential over inflection-point 'speed bumps'
Ting Qu, Deng Pan, Yuliang Jin
The paper shows that the slow, power‑law energy relaxation of quenched structural glasses can be explained by a stiffening caging potential experienced by each particle, without re…
Programming strain-stiffening in soft composites via structural memory near jamming
Yiqiu Zhao, Deng Pan, Yiming Pang +6
Soft composite solids, comprising discrete inclusions embedded within a compliant matrix, are emerging candidates for engineering synthetic tissues and soft robotic materials. Curr…
Universal activated aging and weak ergodicity breaking in spin and structural glasses
Bin Li, Deng Pan, Ting Qu +1
Glasses possess complex energy landscapes and exhibit non-equilibrium aging dynamics. Here, we propose a generalized trap model for activated aging based on a key static property o…
Hierarchical and ultrametric barriers in the energy landscape of jammed granular matter
Shuonan Wu, Yuchen Xie, Deng Pan +2
According to the mean-field glass theory, the (free) energy landscape of disordered systems is hierarchical and ultrametric if they belong to the full-replica-symmetry-breaking uni…
Jamming as a topological satisfiability transition with contact number hyperuniformity and criticality
Jin Shang, Yinqiao Wang, Deng Pan +2
The jamming transition between flow and amorphous-solid states exhibits paradoxical properties characterized by hyperuniformity (suppressed spatial fluctuations) and criticality (h…
Long-range angular correlations of particle displacements at a plastic-to-elastic transition in jammed amorphous solids
Yang Fu, Yuliang Jin, Deng Pan +1
Understanding how a flow turns into an amorphous solid is a fundamental challenge in statistical physics, during which no apparent structural ordering appears. In the athermal limi…
