Activated coarsening of motility-induced phase separation in random environments
Parameshwaran A, Bhaskar Sen Gupta
Self-propelled particles that only repel one another can still separate into a dense and a dilute phase, a process known as motility-induced phase separation (MIPS). In a clean sys…
Two-Stage Ordering Kinetics in Binary Mixtures of Ellipsoidal Particles
Parameshwaran A, Sanjay Puri, Bhaskar Sen Gupta
We investigate the nonequilibrium phase-ordering kinetics of a binary mixture of uniaxial ellipsoidal particles interacting via the anisotropic Gay-Berne potential using large-scal…
Activity-Driven Dewetting and Rupture in Thin Liquid Films
Preethi M, Daniya Davis, Bhaskar Sen Gupta
Thin-film dewetting is classically governed by an adhesion-mediated spinodal instability in which curvature-driven diffusion controls post-rupture coarsening. We show that internal…
Active alignment-driven coarsening in confined near-critical fluids
Parameshwaran A, Bhaskar Sen Gupta
We investigate vapor-liquid phase separation of an active near critical Lennard-Jones fluid confined within a cylindrical pore using molecular dynamics simulations. Activity is int…
Breaking the Logarithmic Barrier: Activity-Induced Recovery of Phase Separation Dynamics in Confined Geometry
Preethi M, Parameshwaran A, Bhaskar Sen Gupta
Phase separation in confined environments is a fundamental process underlying geological flows, porous filtration, emulsions, and intracellular organization. Yet, how confinement a…
Phase separation and rheology of segregating binary fluid under shear
Daniya Davis, Parameshwaran A, Bhaskar Sen Gupta
We employ molecular dynamics simulation to study the phase separation and rheological properties of a three-dimensional binary liquid mixture with hydrodynamics undergoing simple s…
Kinetics of vapor-liquid transition of active matter system under quasi one-dimensional confinement
Parameshwaran A, Bhaskar Sen Gupta
We study the kinetics of vapor-liquid phase separation in a quasi one-dimensional confined active matter system using molecular dynamics simulations. Activity is invoked via the Vi…
Effect of annealed disorder on the plasticity of amorphous solids
Meenakshi L., Bhaskar Sen Gupta
We investigate the effect of annealed disorder on the mechanical properties and plasticity of a modeled amorphous solid by introducing a small fraction of heavy impurities into the…
Characteristics and Correlation of Nonaffine Particle Displacements in the Plastic Deformation of Athermal Amorphous Materials
Meenakshi L, Bhaskar Sen Gupta
When an amorphous solid is deformed homogeneously, the response exhibits heterogeneous plastic instabilities with localized cooperative rearrangement of cluster of particles. The h…
