The Physics of Topological Defects in Glasses
Arabinda Bera, Peter Schall, Timothy W. Sirk +2
Topological defects play a central role in the mechanical behavior of crystalline materials, yet their relevance to amorphous solids has only recently begun to emerge. Over the las…
Shear induced topological changes of local structure in dense colloidal suspensions
Ratimanasee Sahu, Abhishek Kumar Gupta, Peter Schall +2
Understanding the structural origins of glass formation and mechanical response remains a central challenge in condensed matter physics. Recent studies have identified the local ca…
Structural origin of relaxation in dense colloidal suspensions
Ratimanasee Sahu, Mohit Sharma, Peter Schall +2
Amorphous solids relax via slow molecular rearrangement induced by thermal fluctuations or applied stress. Although microscopic structural signatures predicting these structural re…
Reversibility and hysteresis of the sharp yielding transition of a colloidal glass under oscillatory shear
M. T. Dang, D. V. Denisov, B. Struth +2
The mechanical response of glasses remains challenging to understand. Recent results indicate that the oscillatory rheology of soft glasses is accompanied by a sharp non-equilibriu…
Correlations of strain and plasticity in flowing foam
V. Chikkadi, E. Woldhuis, M. van Hecke +1
Via simulations of flowing foam, we connect the high and intermediate density regimes of complex fluid flows into a consistent microscopic picture of deformation. While at and abov…
Microscopic origin of nonlinear non-affine deformation and stress overshoot in bulk metallic glasses
A. Zaccone, P. Schall, E. M. Terentjev
The atomic theory of elasticity of amorphous solids, based on the nonaffine response formalism, is extended into the nonlinear stress-strain regime by coupling with the underlying…
Particle response during the yielding transition of colloidal glasses
D. V. Denisov, M. T. Dang, B. Struth +2
Yielding is central to the relaxation, flow and fracture of a wide range of soft and molecular glasses, but its microscopic origin remains unclear. Here, we elucidate the yielding…
Shear banding of colloidal glasses - a dynamic first order transition?
V. Chikkadi, D. M. Miedema, B. Nienhuis +1
We demonstrate that application of an increasing shear field on a glass leads to an intriguing dynamic first order transition in analogy to equilibrium transitions. By following th…
Visualizing the strain evolution during the indentation of colloidal glasses
Yasser Rahmani, Rose Koopman, Dmitry Denisov +1
We use an analogue of nanoindentation on a colloidal glass to elucidate the incipient plastic deformation of glasses. By tracking the motion of the individual particles in three di…
Resolving structural modifications of colloidal glasses by combining x-ray scattering and rheology
D. V. Denisov, M. T. Dang, B. Struth +2
Glasses have liquid-like structure, but exhibit solid-like properties. A central question concerns the relation between the structure and mechanical properties of glasses, but stru…
Criticality in Dynamic Arrest: Correspondence between Glasses and Traffic
A. S. de Wijn, D. M. Miedema, B. Nienhuis +1
Dynamic arrest is a general phenomenon across a wide range of dynamic systems, but the universality of dynamic arrest phenomena remains unclear. We relate the emergence of traffic…
