Local Structural Signatures of Shear Bands in Metallic Glasses via Electron Nanodiffraction
Huyen T. Pham, Daniel East, Chunguang Tang +4
Structural changes in a glass due to deformation are subtle and difficult to quantify using conventional imaging and diffraction techniques. Additionally, transmission electron mic…

Experimental identification of topological defects in 2D colloidal glass
Vinay Vaibhav, Arabinda Bera, Amelia C. Y. Liu +3
Topological defects are singularities within a field that cannot be removed by continuous transformations. The definition of these irregularities requires an ordered reference conf…

Clustering of negative topological charge precedes plastic failure in 3D glasses
Arabinda Bera, Matteo Baggioli, Timothy C. Petersen +2
The deformation mechanism in amorphous solids subjected to external shear remains poorly understood because of the absence of well-defined topological defects mediating the plastic…
