Collective Behavior of Intelligent Active Brownian Particles in the Presence of a Static Obstacle
Surya Narayan Sahoo, Arabinda Bera, Jiarul Midya
Using computer simulations, we investigate the collective behavior of two-dimensional active Brownian particles (ABPs) with excluded-volume interactions in the bulk and in the pres…
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…
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…
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…
