Universal Jamming Criticality and Self-Organizing Principles from Disorder to the Limit of Perfect Crystalline Order
Jianhua Zhang, Jiaqi Si, Ning Xu +1
While crystals are defined by periodic order, the nature of amorphous solids remains elusive due to their disordered, diverse, and nonequilibrium structures. Here, we focus on jamm…
Orientational phase transitions induced by two-patch interactions
Lingyao Kong, Hua Tong, Hao Hu
For two-patch particles in two dimensions, we find that the coupling of anisotropic patchy interactions and the triangular lattice leads to novel phase behaviors. For asymmetric pa…
Graph Learning Metallic Glass Discovery from Wikipedia
K. -C. Ouyang, S. -Y. Zhang, S. -L. Liu +6
Synthesizing new materials efficiently is highly demanded in various research fields. However, this process is usually slow and expensive, especially for metallic glasses, whose fo…
A mechanical approach to facilitate the formation of dodecagonal quasicrystals and their approximants
Zhehua Jiang, Jianhua Zhang, Mengyuan Zhan +4
The conditions for forming quasicrystals and their approximants are stringent, normally requiring multiple length scales to stabilize the quasicrystalline order. Here we report an…
Ideal noncrystals: A possible new class of ordered matter without apparent broken symmetry
Xinyu Fan, Ding Xu, Jianhua Zhang +5
Order and disorder constitute two fundamental and opposite themes in condensed matter physics and materials science. Crystals are considered the epitome of order, characterised by…
Achieving adjustable elasticity with non-affine to affine transition
Xiangying Shen, Chenchao Fang, Zhipeng Jin +7
For various engineering and industrial applications it is desirable to realize mechanical systems with broadly adjustable elasticity to respond flexibly to the external environment…
Influence of Roughness on Granular Avalanches
Jie Zheng, Yi Xing, Ye Yuan +10
Combining X-ray tomography with simultaneous shear force measurement, we investigate shear-induced granular avalanches using spherical particles with different surface roughness. W…

Ye Yuan, Yi Xing, Jie Zheng +9
Using X-ray tomography, we experimentally investigate granular packings subject to mechanical tapping for three types of beads with different friction coefficients. We validate Edw…
Jamming in confined geometry: Criticality of the jamming transition and implications of structural relaxation in confined supercooled liquids
Jun Liu, Hua Tong, Yunhuan Nie +1
In marginally jammed solids confined by walls, we calculate the particle and ensemble averaged value of an order parameter, , as a function of the distance to th…
Coupling between particle shape and long-range interaction in the high-density regime
Can-can Zhou, Hongchuan Shen, Hua Tong +2
By using long-range interacting polygons, we experimentally probe the coupling between particle shape and long-range interaction. For two typical space-filling polygons, square and…
Friction-controlled entropy-stability competition in granular systems
Xulai Sun, Walter Kob, Raphael Blumenfeld +3
Using cyclic shear to drive a two dimensional granular system, we determine the structural characteristics for different inter-particle friction coefficients. These characteristics…
Intermittent rearrangements accompanying thermal fluctuations distinguish glasses from crystals
Hideyuki Mizuno, Hua Tong, Atsushi Ikeda +1
It is a persistent problem in condensed matter physics that glasses exhibit vibrational and thermal properties that are markedly different from those of crystals. While recent work…
Decoupling between thermodynamics and dynamics during rejuvenation in colloidal glasses
Xiunan Yang, Hua Tong, Weihua Wang +1
We rejuvenate well-aged quasi-2D binary colloidal glasses by thermal cycling, and systematically measure both the statistical responses and particle-level structural evolutions dur…
Realizing negative Poisson's ratio in unstressed spring networks
Jun Liu, Yunhuan Nie, Hua Tong +1
When randomly displacing the nodes of a crystalline and unstressed spring network, we find that the Possion's ratio decreases with the increase of structural disorder and even beco…
Emergence and percolation of rigid domains during colloidal glass transition
Xiunan Yang, Hua Tong, Wei-Hua Wang +1
Using video microscopy, we measure local spatial constraints in disordered binary colloidal samples, ranging from dilute fluids to jammed glasses, and probe their spatial and tempo…
