Geometric indicators of local plasticity in glasses measured by scanning small-beam diffraction
Amelia C. Y. Liu, Huyen Pham, Arabinda Bera +7
The notion of defects in crystalline phases of matter has been extremely powerful for understanding crystal growth, deformation and melting. Many of these discontinuities in the pe…
Unveiling the Asymmetry in Density within the Shear Bands of Metallic Glasses
Harald Rösner, Arabinda Bera, Alessio Zaccone
Plastic deformation in metallic glasses at room temperature leads to the development of shear bands due to shear localization. In many experiments, shear bands have shown local den…
Hedgehog topological defects in 3D amorphous solids
Arabinda Bera, Alessio Zaccone, Matteo Baggioli
The underlying structural disorder renders the concept of topological defects in amorphous solids difficult to apply and hinders a first-principle identification of the microscopic…
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…
