Shear-induced rigidity of frictional particles: Analysis of emergent order in stress space
Sumantra Sarkar, Dapeng Bi, Jie Zhang +3
Solids are distinguished from fluids by their ability to resist shear. In traditional solids, the resistance to shear is associated with the emergence of broken translational symme…
On the route to shear jamming, are fragile states real?
Ling Zhang, Jie Zheng, Jie Zhang
Starting from an unjammed initial state, applying shear to a granular material of a fixed packing fraction below , i.e. the isotropic jamming density of frictionless spheres c…
The origin and nature of Boson Peak: the normal mode analysis of disordered granular crystals
Ling Zhang, Jie Zheng, Jie Zhang
Despite extensive theoretical \cite{GanterPRL1998, ElliotPRL2001,SchirmacherPRL2007, TanakaNatureM2008, MonacoPNAS2009, MarruzzoSCIRP2013} and experimental studies \cite{ChumakovPR…
Fluctuations of particle motion in granular avalanches - from the microscopic to the macroscopic scales
Ziwei Wang, Jie Zhang
In this study, we have investigated the fluctuations of particle motion, i.e. the non-affine motion, during the avalanche process, discovering a rich dynamics from the microscopic…
Origin of Rigidity in Dry Granular Solids
Sumantra Sarkar, Dapeng Bi, Jie Zhang +2
Solids are distinguished from fluids by their ability to resist shear. In traditional solids, the resistance to shear is associated with the emergence of broken translational symme…
Fluctuations in Shear-Jammed States: A Statistical Ensemble Approach
Dapeng Bi, Jie Zhang, R. P. Behringer +1
Granular matter exists out of thermal equilibrium, i.e. it is athermal. While conventional equilibrium statistical mechanics is not useful for characterizing granular materials, th…
