Unifying Plasticity in Ordered and Disordered Matter using Topological and Geometrical Descriptors
Xin Wang, Yang Xu, Jin Shang +5
Identifying the regions responsible for plastic flow in amorphous solids remains an open problem, since structural disorder seems to prevent the direct application of concepts such…
A flat-band perspective on the boson peak in amorphous solids
Shivam Mahajan, Long-Zhou Huang, Cunyuan Jiang +4
The boson peak is a characteristic anomaly of amorphous solids broadly defined as a low-energy excess in the density of states and heat capacity compared to the textbook prediction…
Three-stage melting of a macroscopic continuous spacetime crystal
Guoqing Liu, Jimin Bai, Matteo Baggioli +1
A spacetime crystal is a phase of matter that spontaneously develops periodic order in both space and time. Spacetime crystals have been experimentally observed in microscopic quan…
Torque Hyperuniformity in Frictional Granular Matter - Theory and Experiments
Jin Shang, Jie Zhang, Itamar Procaccia
A question of some fundamental importance is whether a given assembly of frictional granules (say sand or powder) will exhibit stress autocorrelations with long-range anisotropic d…
Lift force in chiral, compressible granular matter
JarosÅaw PawÅowski, Marcin Dudziak, Matteo Baggioli +2
Micropolar fluid theory, an extension of classical Newtonian fluid dynamics, incorporates angular velocities and rotational inertias and has long been a foundational framework for…
Topological defects govern plasticity and shear band formation in two-dimensional amorphous solids
Xin Wang, Jin Shang, Yujie Wang +2
Understanding the fundamental mechanisms behind plastic instabilities and shear band formation in amorphous media under applied deformation remains a long-standing challenge. Lever…
