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…
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…
Burgers rings as topological signatures of Eshelby-like plastic events in glasses
Arabinda Bera, Ido Regev, Alessio Zaccone +1
Eshelby-like quadrupolar structures serve as the fundamental microscopic units for characterizing plastic instabilities in amorphous solids and play a crucial role in explaining th…
Microscopic origin of shear bands in 2D amorphous solids from topological defects
Arabinda Bera, Debjyoti Majumdar, Timothy W. Sirk +2
The formation of shear bands in amorphous solids such as glasses has remained an open question in our understanding of condensed matter and amorphous materials. Unlike in crystals,…
Density-field structures in a few systems undergoing velocity ordering
Subir K. Das, Sohini Chatterjee, Wasim Akram +3
We consider two (off-lattice) varieties of out-of-equilibrium systems, viz., granular and active matter systems, that, in addition to displaying velocity ordering, exhibit fascinat…
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…
